Customers highly appreciate our product for its top-notch quality, particularly praising its phenolic resin inner, which ensures better heat transfer. Users have found it practical, fitting perfectly and reducing carburetor temperature significantly, with one reviewer noting a 35-degree drop. Some users did encounter a minor issue with the cross in the spacer; however, it was easily rectified. In comparison to competitors, our product stands out as the more superior choice, echoed by a user's willingness to repurchase the adapter. Its usability, quality material, and safety make it a worthy purchase for customers.

This is old school carburetor spacer/heat dissipater quality. Works so well on intake manifolds with a plenum divider.

I was trying to use this on a 670 Holley on a 350 GM aluminum intake. The description reads to use this for 4150 series witch is what a 670 is. The problem was the butterflies would not clear the cross in the spacer. I cut the cross out and everything cleared. Will know for sure when I fire the engine. I think if I would have ordered the open spacer I would have been fine.

The spacer was exactly as described, fit perfectly and is working as expected, reducing carburetor temperature by about 35 degrees compared to the intake manifold.
