These are awesome for a DIY intake on Magnum360. Great fit and finish. Will fit GM350 and many others I am sure. Coupled with 4” silicone boot, 4” aluminum tube cut down, to a Donaldson filter, with RiffRaff pre-filter. All but the pre-filter came from Amazon.

I had a makeshift cold air intake but it was only 3”. I wanted a 4” and have looked at this for over 2 years. Well I finally did it and I love it!They sell the carb hat, tube and an inline air cleaner. It wasn’t cheep but I now have a 4” ram scoop cold air intake and I am super happy I finally did it.The carb hat is nice. I still think it’s far too expensive but there are no other options.Fits a 4 barrel perfectly.Tube runs below my front bumper to pick up air as I drive.

I purchased this to build a cold air intake system for my new fuel injected motor for my 71' Dart. The product is great and a good piece. Will work as intended. But I unfortunately was unable to use do to lack of hood clearance. The plenum is 3.5" So you need more than that for it to fit properly. I only had 3.5" so I knew it would be close. I even had a CNC shop mill off 1/4" of extra material on the lower mounting flange. It still wasn’t enough. The height was now clearing the hood but the 4" inlet that extaneds out away from the the Carb. was hit a section of the hoods bracing. It being a original hood for my 71' Dart I'm not to keen on cutting it up to make it fit. So I opted to purchase their low-profile version instead. Now I have to try and sell this one and try and recoup my money.

Cast aluminum construction, so you will need a Dremel to cut the pieces of casting flash off of the ID of the Carb hat.Pretty good looking to compliment the rest of the chrome ducting I had fabbed up previously.Still a bit on the expensive side, considering the slop, the hat would slide around even on top of a carburetor mounting flange of 5 1/8.When bolted down, looks good and no shimmy.

Was surprised at how well this was made. Heavy duty cast aluminum not some cheap folded tin material.It will work out great for me to add a cold air intake system on my class A RV.

This looks like a great air intake plenum.... The correct size for a standard carburetor type air filter location install,Came wrapped up in a non scratch bag in a nice box ....It's correctly machined and has a great shine on it also.... I'm a happy customer

funciona perfecto , le puse una manguera de 4" y ya puede instalar un filtro de alto flujo en otra parte del coche, no tuve problemas con la altura en un malibu 81, apesar de tener un plato adaptador para un carburador street demon.

Item is as described. It's a brilliant item unfortunately didn't fit my purpose. My fault. I didn't measure properly. I would definitely do business with Amazon again. Fast sending and items are as described.
