Throttle Body Spacers Reviews
Check out this recent aFe Silver Bullet Throttle Body Spacers customer review: George Y from Angleton, TX says "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."

Jet Performance Power-Flow TBI Spacer

Jeep YJ 4.0L throttle body spacer review

Took less than 10 Minutes to install, noticed a change in sound from engine. Upon driving my Jeep I also noticed better response form the throttle especially in 3rd thru 5th gear, my Jeep pulls harder and longer than before. The extra power helps turn the over sized tires better. I recommend this product. Not a ton of power gained, but it was noticeable. View more reviews...
