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.

Excellent sound, better performance and response, and high quality product. I've installed it in my Sierra Denali 6.2.

I just wanted to say that I love it. Installed it on my 2013 GMC Denali pickup 6.2L. It wasn't that difficult to install. I am disabled with rheumatoid arthritis and the instructions were somewhat easy, but mechanical skills probably helped a lot. I have noticed the difference in the sound and power. Just wanted to say thanks for a good product that will last for years. Thanks, Edwin. P.S. Some more stickers would be nice. .

Gave my truck more bass while idling (5.3L), improved take off, improved fuel economy, sounds quite a bit more aggressive when shifting into passing gear on the interstate and down shifted less when going up long grades. Felt like the truck was trying to walk away from me. If you're it's concidering a cold air intake, I highly recommend K&N. -Lillard
