The K&N air filter arrived on time, exactly as described on the Web site, in good condition, and performs flawlessly after almost 5,000 miles. Based on past experience with K&N, this will be the last intake filter I purchase for this vehicle.

Have had K&N filters in my past 2 vehicles. Ordering the replacement for the 2014 Tacoma was a no-brainer as soon as I got settled in the truck. K&N filters smooth out the power curve, especially in a 6. Would never own another vehicle without one.

Loyal K&N customer since 1995. Every vehicle (4) I have had since then has had a K&N in it. Great product!!!!
