K&N air intake for 2003-2004 Toyota Tundra 3.4L V6

By reducing intake tract restriction and increasing airflow, a 2003-2004 Toyota Tundra 3.4L V6 can experience a guaranteed increase in horsepower

During the 1980’s and 1990’s Toyota’s legendary reputation for building a reliable and economical pickup helped to cement Toyota’s position in the compact pickup truck market. It seemed only logical that Toyota would enter into the North American full-size pickup truck market and so Toyota did in 1993 with the Toyota T100. However, Toyota’s first attempt at taking a bite out of the Big Three automakers’ share of the full-size pickup market was relatively unsuccessful. Although the T100 was economical, and affordable, it was still smaller than its competition and lacked the option of a V8 engine.

Not to be discouraged, Toyota came out swinging in 1999 with the all-new Toyota Tundra introduced for the 2000 model year. In comparison to its predecessor, the 2000 Toyota Tundra was larger and for the first time a Toyota truck had a 4.7L I-Force V8 engine as an available option. Toyota carried over the tried and true 3.4L V6 engine as standard equipment, however Tundra owners who opted for the 4.7L I-Force V8 were rewarded with 150 more horsepower and 100 lb-ft more torque than the V6. K&N has made upgrading performance first generation 2000, 2001, 2002, 2003, and 2004 Toyota Tundra 3.4L V6 easy for owners with the superior filtration and superior performance that K&N is famous for.

In comparison to its predecessor, the Toyota T100, the 2000 Toyota Tundra was larger and for the first time a Toyota truck had a 4.7L I-Force V8 engine as an available option

A K&N replacement air filter 33-2144 is an easy 5 minute upgrade for 2000-2005 Toyota Tundra pickups with the 3.4L V6. For a guaranteed increase in horsepower, a 2000, 2001, or 2002 Toyota Tundra 3.4L can be upgraded with a K&N air intake system 57-9019. By reducing intake tract restriction and increasing airflow, this air intake was able to provide an estimated 5.02 additional horsepower on an otherwise stock 2000 Toyota Tundra 3.4L. Owners of 2003 and 2004 3.4L V6 Tundra models should purchase K&N performance air intake 63-1043.

Toyota’s 4.7L I-Force V8 is a capable engine, however that doesn’t mean that owners couldn’t use a little extra horsepower, torque, and throttle response for towing, passing, or daily driving. 2000-2006 Toyota Tundra 4.7L V8 models have an easy drop-in performance air filter option from K&N 33-2144. In addition to the high-flow air filter upgrade, K&N offers a performance air intake system for the Toyota Tundra.

2003-2004 Toyota Tundra 4.7L V8 owners can choose an aluminum air intake system 77-9020KP with a mirror like finish shown to make an estimated additional 10.8 horsepower. Or for a more original equipment look, K&N offers air intake systems made with black rotationally molded high-density polyethylene (HDPE). The roto-molded HDPE air intake tubes offer more flexibility in design, and often times a greater increase in power over an equivalent aluminum air intake.

K&N air intake 77-9027KP for 2005-2007 Toyota Tundra 4.7L pickups

A choice of a mirror like aluminum air intake, 77-9027KP, or a black roto-molded HDPE air intake, number 63-9027, is offered for owners of 2005, 2006, and 2007 Toyota Tundra 4.7L pickups

2000 and 2001 Toyota Tundra 4.7L V8 models can be equipped with K&N air intake 57-9014-1 that has been tested on the dyno to provide an estimated 14.2 more horsepower. 2002, 2003, and 2004 Toyota Tundra 4.7L I-Force V8 owners can benefit from installing K&N air intake 57-9020 which was shown to provide an estimated additional 13.68 horsepower gain.

2005 brought some big changes in the power department for the Toyota Tundra. The 4.0L 1GR-FE V6 engine, brought over from the new second generation Tacoma, replaced the 3.4L V6 as the Toyota Tundra’s standard engine. The 2005 Toyota Tundra 4.0L V6 was rated at 236 horsepower, which was only 9 less horsepower than the 2004 Toyota Tundra 4.7L I-Force V8. Simple performance upgrades for the 2005-2006 Toyota Tundra 4.0L V6 can help, or potentially eliminate, that horsepower gap. A K&N high-flow replacement air filter 33-2281 is an excellent start to upgrading 2005-2006 Toyota Tundra 4.0L performance. However, one of the best bangs for the buck is a high-flow K&N air intake system.

2005 Toyota Tundra 4.0L V6 engine with K&N air intake

2005 brought some big changes in the power department for the Toyota Tundra, the 4.0L 1GR-FE V6 engine was introduced, and the 4.7L 2UZ-FE V8 received VVT-i technology

Owners of 2005 and 2006 Toyota Tundra 4.0L V6 models can choose from a mirror like aluminum air intake system 77-9028KP shown to provide an estimated additional 8.33 horsepower or a black HDPE air intake K&N air intake number 63-9028. When tested on a 2005 Toyota Tundra 4.0L, 63-9028 was shown to provide an estimated additional 11.43 more horsepower at 5,159 RPM.

Not to be outdone by the 4.0L 1GR-FE V6 engine from the Toyota Tacoma, Tundra engineers upgraded the Tundra’s 4.7L I-Force V8 engine with variable valve timing (VVT-i) technology. This increased the 2005 Toyota Tundra 4.7L V8’s horsepower rating up an additional 40 horsepower and nearly 60 lb-ft of torque. An engine with variable valve timing can often benefit from the increased airflow and reduced restriction offered by a K&N air filter.

K&N cold air intake for 2007-2011 Toyota Tundra 5.7L pickup trucks

2007-2011 Toyota Tundra 5.7L pickup trucks can quickly bolt on an estimated horsepower gain of over 13 horsepower with the mirror like aluminum air intake, number 77-9031-1KP

2005-2006 Toyota Tundra 4.7L models can receive a quick boost in performance from K&N replacement air filter 33-2144. Better yet is the increased performance and guaranteed increase in horsepower offered by a K&N air intake system. A choice of a mirror like air intake aluminum air intake 77-9027KP, or a black roto-molded HDPE 63-9027 can offer owners of 2005, 2006, and 2007 Toyota Tundra 4.7L pickups an estimated increase of 8.69 and 9.54 additional horsepower, respectively.

While the Tundra was larger than its predecessor, the T100, and offered a V8 engine it was still criticized as undersized and underpowered compared to larger full-size trucks from American automakers Ford, Chevy, and Dodge. So once again Toyota took on the Tundra’s critics by introducing the larger second generation Toyota Tundra for the 2007 model year. The second generation effectively squashed complaints about the Tundra being small, but the second blow came from Toyota with the introduction of an all-new 5.7L 3UR-FE V8 engine. The dual VVT-i 5.7L V8 was rated at a whopping 381 horsepower and 401 lb-ft of torque. The 4.0L 1GR-FE V6 engine was still slotted as standard equipment for base models, and the 4.7L 2UZ-FE I-Force V8 was still offered in 2007.

5.7L 381 horsepower Tundra using K&N air intake for extra power

The 5.7L 381 horsepower and 401 lb-ft of torque second gen Tundra’s 3UR-FE engine has plenty of power for most situations, however, there are times where a boost in power is handy

The power of the 5.7L V8 engine might leave owners of 4.0L V6 powered second generation Toyota Tundra pickups searching for a little extra power. 2007, 2008, 2009, and 2010 Toyota Tundra 4.0L trucks can be upgrade with a simple drop-in replacement air filter, number 33-2281, or the choice of two K&N air intake systems. Aluminum air intake 77-9033KP was shown to provide an estimated 9.68 more horsepower for a 2007 Toyota Tundra 4.0L and black HDPE air intake 63-9033 shows a similar estimated horsepower gain. Owners of 2011, 2012, 2013, and 2014 Toyota Tundra trucks with a 4.0L V6 engine can upgrade their truck simply with the installation of high-flow replacement K&N air filter 33-2387. The 4.0L V6 engine has been dropped from the Toyota Tundra’s list of available engines for the 2015 model year.

The same performance air filter that fits 2011-2014 Toyota Tundra 4.0L V6 trucks will add performance to 2007-2013 V8 powered Toyota Tundra pickups. The Toyota Tundra received a face-lift for the 2014 model year. But with those visual changes also came some slight mechanical changes. One such change was an all-new stock air filter box. This required K&N engineers to develop K&N high-flow replacement air filter 33-5017 for 2014-2017 Toyota Tundra V8 models.

K&N air intake system for 2010 Toyota Tundra 4.6L

K&N air intake system, number 63-9035, was shown to provide an additional estimated horsepower gain of 13.75 HP and 10.61 lb-ft of torque on a stock 2010 Toyota Tundra 4.6L

The 4.7L I-Force V8 first introduced in the 2000 Toyota Tundra, and later updated in 2005, continued to be offered in the second generation Tundra for 2007, 2008, and 2009. 2007-2009 Toyota Tundra owners who could use a little extra horsepower, without the expense of the 5.7L V8 upgrade, can count on K&N to provide a guaranteed increase in horsepower and torque. With the installation of a black HDPE air intake system 63-9032-1 or aluminum air intake 77-9032-1KP, 2007-2009 Toyota Tundra 4.7L V8 trucks can increase horsepower by an estimated gain of more than 8 additional horsepower.

In 2010 Toyota replaced the 4.7L V8 engine with a 4.6L 1UR-FE V8 engine originally used in Lexus models in the Middle East. This new smaller engine belongs to the same engine family as the Tundra’s 5.7L engine. It shares the 5.7L engine’s 94 mm bore, but with a shorter stroke. 2010-2015 Toyota Tundra pickups with the 4.6L engine can bolt on a K&N air intake system for an upgrade in performance in around 90 minutes. Black HDPE air intake system 63-9035 was shown to provide an additional estimated horsepower gain of 13.75 horsepower and 10.61 lb-ft of torque on an otherwise stock 2010 Toyota Tundra 4.6L. 2010-2015 Toyota Tundra 4.6L owners who want to improve their trucks appearance and increase horsepower can do so with K&N’s aluminum air intake system 77-9035KP.

Toyota replaced the 4.7L V8 engine with a 4.6L 1UR-FE V8 engine

Toyota replaced the 4.7L V8 engine with a 4.6L 1UR-FE V8 engine originally used in Lexus models for the Middle East however, this new engine belongs to the same family as the 5.7L V8

The 381 horsepower and 401 lb-ft of torque offered by the second generation Toyota Tundra’s 5.7L 3UR-FE V8 is probably more than enough power for most situations. However, there are times such as towing, hauling a fully loaded bed, or even off-roading where a boost in horsepower can come in handy. Once again K&N has stepped in to offer a bolt on performance upgrade that can be installed in around 90 minutes and with basic hand tools for the 5.7L Toyota Tundra.

2007-2011 Toyota Tundra 5.7L pickup truck owners can quickly bolt on an estimated horsepower gain of over 13 horsepower with black HDPE air intake system 63-9031-1, or the mirror like aluminum air intake 77-9031-1KP. Both of these air intake systems are guaranteed to increase horsepower and performance and are backed by a lifetime limited warranty. 2012, 2013, 2014, 2015 and 2016 Toyota Tundra 5.7L pickups can also bolt on more horsepower with either black roto-molded HDPE air intake 63-9036, or aluminum air intake system 77-9036KP.

So now that the Tundra is big, has a powerful 5.7L V8 engine, and can tow just as well as the competition, what’s left for the critics to complain about? Hardcore fans of the Big Three automakers certainly can’t complain about the Tundra being foreign built, as it has always been assembled in the U.S. As pickup trucks with diesel engines continue to grow in popularity it is plain to see that Toyota is leaving a gap in its offerings. In 2007 when the Tundra was first introduced Toyota showcased a diesel powered dually Tundra concept to target the heavy duty ¾ ton pickup market. Unfortunately a down turn in the global economy and slumping sales put a diesel powered Tundra development on hold. Perhaps the third generation Toyota Tundra will once again utilize a list of first-time offerings for a Toyota truck.
