Canton Racing Products"85-154 Phenolic Carburetor Spacer (For 4150/4160 Holley 4 Hole 1/4"), 1 Pack"

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

Perfect fit for Holley sniper EFI.

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!!!

This was used to prevent heat transfer to my Holley Sniper.Just enough clearance .Just a little pricey though.Other than that, it's working good!

Top quality product. I needed to modify it for my use on a "65 Corvette because this is a 4 hole spacer and I needed one side to have two holes and the other side to be open. So I sawed the web between the two holes and made it totally open to match my stock aluminum intake manifold. Works great!

I used this on my Holley Sniper EFI system after experiencing the dreaded loud whistle at about 30% throttle. This spacer not only eliminated the whistle, but it keeps the throttle body much cooler than before; which is critical with the Sniper system because the ECU is part of the throttle body. Also, the bore holes are 1 3/4", which means the throttle blades and air flow will not be impeded by the gasket.I tried the Mr Gasket 758 before this and it started falling apart right out of the package and the bore holes were smaller than the throttle body bores. I threw the Mr Gasket in the trash and ordered this.

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.

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!

as advertised
