The K&N 63-1132 AirCharger air intake system replaces the restrictive factory air filter and air intake housing on specific BMW 535i models. K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install, usually in 90 minutes or less using your vehicle’s existing factory mounting points. The tools needed are a screwdriver, ratchet set, pliers and several wrenches.

K&N 63-1132 Air Intake Product Reviews

Wednesday, June 13, 2018 - Part 63-1132
The product was as advertised. I was looking for additional hp without a major modification to my BMW. I noticed the first time I drove the car after the install a feeling of quicker response to the throttle. The install was quite easy and took no time at all. I would modify the instructions that were given. I built the air filter and housing together on the workbench first (much easier) then connected the assy. to the air intake with the clamp (keeping it loose) then fit it to the existing BMW housing with the five supplied screws then tightened the hose clamp. My biggest concern is the sealing method to the inside of the hood insulation (see picture called dirt inside of hood). It appears that road dirt is coming from around the seal and blowing into the engine compartment. Also the connection that the air filter clamps to has an air gap around the box housing (not a tight seal) see picture called light gap. I had a flashlight backlighting it. Question, can I cover the top of the open box to keep a better seal or does that defeat the purpose of the cold air flow system.

I was skeptical at first, but I could truly feel an increased throttle response. Changes the depth tone of my car as well. I am sure others will enjoy this product.
