K&N Performance Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 77-3070KP

Great service, great product and instant satisfaction once installed! This is my second K&N cold air intake. My first was for a 2005 Chevy Silverado. Purchased this SKU for a new 2013 quad cab 5.3L Chevy Silverado 1500 Z71 LTZ. I love the increase in horsepower and the throaty sound (when I punch the gas) from my new K&N cold air intake. Will buy again for every truck I buy. Thank you K&N Store for the shipment updates, great price and excellent product - the careful packaging as well as hasty delivery was exceptional. 5 stars from me as always.

The product was easy to install (77-3070KP). It took me about an hour to install by just reading the instructions and doing what they said. I am not a mechanic but it is pretty straight forward. The sound is great and the power is nice when pulling a trailer. The gas mileage I am still checking. Good product and good service. I would recommend this company and product.

After installing this CAI on my 2011 Silverado crewcab 4wd with the 6.2 liter my fuel mileage has increaed by about 2 mpg in both city and highway. As far as power increase I am not sure but the truck seems to be a little more responsive. Noise level under hard acceleration is quite a bit louder but under normal accerleration it is not noticably louder. Installing the product took about 3 hrs. Instructions were easy to read and understand. Overall I would recommend this product.

Item arrived packaged very well. Everything was intact and complete. Installation went fairly easy following the instructions. Process is pretty straight forward. Can definitely notice a quicker throttle response and it sounds a little deeper and throaty. Overall I'm very satisfied and would definitely reccomend to other friends to use your products. Haven't had it long enough to notice any difference for fuel mileage, but I'm sure that will improve a little if I can stay off the throttle!

Love the product! The 77 series is the first K&N product I've purchased. Gives off a really nice sound. Looks awesome. Diffidently more power and fuel economy. Relatively easy to install a little bit of drilling but nothing major. I am very impressed with the product. I will never buy anything but K&N!

I had a K&N filter in my 2011 Chevy Silverado and in my 2004 Silverado, I put a Spectra cold air system in the 2004. Both systems look good and are getting more air to these trucks !

The time from when I ordered it till I received it was very quick. The install instructions were easy to understand. It took about 1.5 hours to install. I would definitely go with K&N again and recommend it to a friend.

I have a fresh air inlet on my 2003 one ton diesel dully, on my 2010 GMC, 5.3 engine and on my 2007 Ford Edge. your KN air filter and synthetic motor oil saves me a bunch on fuel. Love your products.

This product was easy to install. It was well built and performs great! You won't regret it. It's excellent. On a side note the instructions provided were clear and concise.

I like the product it does seem to help with mileage. Jegs did me wrong though ordered 2 days later jegs sent an email on how they had reduced the price by right at $30. That sucked big time
