According to the first trip I made I picked up 4 mpg. Very impressed so far!!!

Received the spacer in a few short days. Well designed and fits to the intake perfectly. No whistling noise heard when running. Power increase wasn't pronounced but that would need a dyno test before-and-after installation for measurement. Spacer is used in combination with cold-air intake and cat-back exhaust. Together made major improvement in acceleration.

This intake is the best on the market. Major hp gains especially at high rpms and take offs!! Really recommend it to everyone. Install was super easy even with no mechanic background
