Performance SPE-9741 Black 4" x 3.5" Intake Coupler

Needed replacement for my 06 Avalanche, using K&M air filter intake tube. Couldn't find replacement from any part stores, NAPA wanted $65 for 1 ft piece of rubber tube (that i would have to cut down, and didnt include pipeclamps). This adapter came with 2 hose clamps and worked good on my truck, a bargain, will probably order another one to have as a spare

I recently put a BOSS 302 intake manifold in my 2014 Mustang 5.0, and I added an Accufab throttle body along with a JLT CAI. I needed a coupling like this in order to connect the TB and CAI of course, and they're two different diameters. This did the trick and everything is connected all snug! Even held up through DynoTune and didn't break loose or anything. Great quality, would recommend.

Just what I need for my install and fit perfect.

Works great for a wet exhaust adapter for my boat, needed to go from a 3.5" mixer to a 4" exhaust set-up. The hose clamps aren't great, but would probably work fine for a car intake. I replaced them with t-bolts. The coupler seems to be good quality reinforced silicone too, and it's fairly stiff, rather than the soft rubbery couplers. I bought another to have a spare on board.

I bought this to install a MAF onto a 4" intake tube. Works great when doing an LS swap into a hotrod and building your own air intake which is almost always needed. On LS motors, the throttle body is 4" diameter, and on the 75mm MAF's both sides are 3.5". On the 85mm MAF, one side is 3.625" the other is 4". This will work on the 3.625" side of the 85mm MAF.

Solid material, feels flexible but sturdy, seems to resist good to high temperatures. Another good Spectre product.

Item is very good quality and it fit like a glove. Super inexpensive for the quality.

Looks great, worked great and shipped fast. Looks and works perfect on my cold air intake I put on my 01 yukon 5.3

Fit as expected and seems to be of good quality. Will have to see how it holds up in the long run but good value for the price.

Good quality rubber, dimensions as described

works well

Perfect fit and price, looks well made

Fits perfect for my 5.3 mass air flow sensor. Doing a 2000 5.3 swap
