    • Quality is thumbs up!
Why did you pick this product vs others?: The reputation of high performance and quality!! However the instructions are kinda vague. I wound up looking at the diagram and assembling the air kit by the picture only!!

Horrific instructions. Call customer service and they will email you an amazing version. Once you get the instructions then you’re set. Smooth sailing after the good instructions. It kicks butt. Great purchase. Stoked.

    • K&N rocks!
Product installed 3 days ago. Love it on my 02 Tacoma 2.7! The most obvious improvement is throttle response. This product has definitely increased HP and acceleration for my truck. It also sounds a little meaner, previously thinking that was not possible.

    • K & N (Nuff said)
All of my cars and bikes have K&N. The brand name speaks for itself. The instructions could be better for those who aren't familiar with installation. Always be careful when tightening the plastic nipples, they strip or break easily. Noticiable difference in acceleration and gas mileage. Love the throaty sound of the engine when accelerating as well. Get one and install it now! ... show more

Showed up and performed as described nothing more nothing less. Can’t ask for anything better. Make sure to put your Mass Air Sensor back on in the correct position and get the vacuum tubes correct. 1 hr install

    • GREAT PRODUCT! 5 STARS ALL THE WAY THROUGH
To anyone who is even remotely considering adding an Air Intake to their car/truck, this is the one you want. I put it on my 2004 Toyota Tacoma 2.4 Liter and it made a HUGE difference. Added Torque, HP and increased my MPG. Absolutely love it and would definitely recommend it. -Dan G
