Comments about Airaid PowerAid; Throttle Body Spacer:
I'd consider this a mandatory performance upgrade if you have a 2.8 or 3.1 TBI engine (this spacer has the smaller bore used on the 60-degree engines, not the large-bore of the 4.3 and V8 TBI systems). Significantly sharpened up the throttle response on my old Rodeo's Chevy 3.1, moved the torque peak about 500 rpm lower (according to my seat-o-meter) and took my fuel economy from 17 to 18. I did have to replace the crankcase breather hose with one about 3 inches longer to compensate for the height of the spacer.

Q:What size/kind of bolts are used for this tbi spacer? I lost my hardware and want to buy new hardware but don't know the size and bolt type. I just know the 3 washers are 8mm. Thanks.
A:Glad I could help! Three 5/16-18-inch x 3 1/4-inch bolts and three 5/16-inch washers are included in this Throttle Body Spacer.
