"Use them to replaced my intake manifold bolts on my 95 Chevy blazer."
"Perfect replacement part with a dress up look."
"Look so much better than hex head bolts holding your intake on."
"I needed a little extra length to accommodate some emissions/throttle brackets that mount with the intake bolts."
"In my opinion better than originals and allows more room to install nd removed with its head design."
"Appears that the package was opened and dumped into the shipping box and was missing 3 washers."
"I bought these based on the Amazon determination that they fit my engine (a 1999 4.3L 90 deg V6) but they do not fit."

Best Automotive Performance Engine Intake Manifold Spacers

aFe Power Silver Bullet 46-35002 Jeep Throttle Body Spacer
