I use K&N on all my vehicles, great product.

The install was a breeze. I noticed the more masculine motor noise immediately and the quicker acceleration, especially when you factor in how heavy my 4X4 Chevy Trailblaser 4.2 L6 is. Don't know if my MPG has improved but so for I'm happy. I will be getting the air intake components next.

Works good on my Saab with the Vortec 4200 straight six. I feel like it would work alot better with the whole intake kit, filter and the duct work. I got a little more power but that air box is very restrictive.
