L36 Throttle Body Spacer


10 reviews

This product is currently out of stock.

This 1/8" spacer adds slight volume to the upper intake, and prevents the coolant from heating up the throttle body. These things translate into more power with less KR.


Spacer seals to the intake with the OEM rubber gasket. Throttle body seals to intake with RTV or GM adhesive (recommended).


Fits any engine with the front wheel drive L36 non-supercharged series II engine.

Does not fit rear wheel drive applications for example Camaro/Firebird.

Noticeable gains

Was slightly shocked at how thin and small this spacer was. It looks like a gasket. Let me tell you what a noticeable difference in the mid range rpm this ridiculous thin piece of plastic does. My LeSabre is bone stock aside from an eBay short ram intake, and when I installed the spacer, throttle response improved and mid range power and acceleration was greatly improved. Funny how such a small things can make a huge difference. I have an L67 spacer and ported TB on my Bonneville and the L67 spacer is huge, but makes a big differences. It’s worth the $25 for that extra little kick and the 20 mins it takes to install.
