2003 Isuzu Ascender 4.2L L6 - All Models
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.
