Worked great for taking the whistle sound out of the Holley sniper

High quality part. I needed a little extra clearance with the new carb I installed. It should also keep the carb a little cooler.

I thought I would order this to try, as most carb spacers are minimum 1/2", and on my 1967 Plymouth I am fighting hood clearance. The description and reviews seem to only mention compatibility with Holley carburetors, but this went right onto a Edelbrock 7193 Performer RPM intake, and no issues with primary or secondaries opening on a Edelbrock 1906 AVS2. Perfect fit.

This is a well made spacer that fits the Holley 4150 flange perfectly.I used this on a single plane intake to improve vacuum signal at the carburetor boosters and it worked great. Noticeable improvement in low-end throttle response - and much better adjustability of the 4-corner idle circuit.Recommend using a wide-band O2 sensor to adjust carb tune, because with a spacer the carb jetting requirements may change slightly.

I didn’t like the price a little ridiculous. Insulating the carb so the heat doesn’t boil out the gas when shut off.

Once I install this on my Holley EFI sniper you could feel the temperature difference after I drove it the throttle body wasn't even hot at all basically room temperature

Just like the other reviews say this spacer is a must for use with Holley Super Sniper EFI. My Sniper with an "open" 1/2" Phonelic spacer from Jomar made a squealing/sucking sound around half throttle, Showed lean AFR's and had lean-pop sounds on deceleration. My intake isn't anything special but it is a dual plane with the divider milled down. This four hole spacer fixed ALL of the above issues and it runs amazing!!!If you have a Holley Sniper or Super Sniper this is a must!!!

Lo compre por que leí que eliminaba un silbido en el cuerpo de aceleración del Sniper EFI además de ayudar a aislar el calor de la admisión y fue todo un éxito!

Good quality workmanship, symmetrical tight fit for square bore manifold. Used with Holley 4160 carb to get proper throttle mechanism clearance on a stock Mopar 67 440HP manifold. I'll also vouch for it's helping reduce heat transfer and minimize vapor lock . It is said that a 4 hole spacer cano help with low end power and eliminated an off-idle stumble -it did just that for my application.

The spacer itself is a nice product, but nowhere in the description does it indicate that the gaskets are not included. The description does recommend a stud kit as an adder, but no mention of gaskets. This is the first question that comes to mind when ordering, so a simple update to the product description would be recommended.
