The K&N 71-3070 Blackhawk Induction Air Intake System is a free-flowing, mandrel-bent aluminum tube air intake system that is guaranteed to gain power. It replaces your vehicle’s restrictive factory air filter and air intake housing. This low restriction air intake allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more power and acceleration. This K&N Blackhawk Induction Air Intake System comes with black components including the K&N high-flow air filter and heat shield. The attractive textured black powder-coated finish tube features an engraved K&N plate welded on to which gives it a clean, high-performance look under the hood. The intake tube accommodates the factory mass air sensor and a replacement silicone crank case vent hose. The oversized cone shaped air filter is made from an oil-free synthetic filter media that can be used for up to 100,000 miles before cleaning is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points using commonly available tools. Some K&N Blackhawk Induction Systems are not legal for sale or use in California and other states adopting California emission standards while others are 50 state legal.

K&N 71-3070 Air Intake Product Reviews

Monday, February 13, 2017 - Part 71-3070
I Dinged 1 star just because the directions could be more clearly written, especially if you have little experience wrenching. It wasn't difficult at all. It just could have been a bit clearer. That said; what a great set up. It went on in about an hour and the parts provided seem to be of excellent quality. You really can't hear it breathing until you step down hard on the gas. Then, It makes such a beautiful sound. Next up for my truck is a better exhaust system to really get the truck breathing and a tuner module.

I have been driving my truck for a few months now. It is my daily so I drive roughly up to 2,000 miles each month. Yes it does sound bad @$$ and yes it looks super clean under the hood but, it did not improve the performance or improve fuel efficiency like people say. Overall its an okay product.
