Matthew Mason –
like all spectre products this is really good quality. it worked on my carb for my jeep. it is kinda tall so the hood hit the hose for it a bit, but it is a good quality item that came in fast and has lasted years. wanted to wait a while before writing anything to see how well this worked. so if your making a cold air intake this is acceptable for the job.

Used two of these on a JEGS hot road heater in my jeep, the duct hose is 2.5″ and the openings on the heater are 3″ for reasons unknown. Worked great, had to trim one down and was easily done with a razor blade.

Works fine like intended

Made of good material and the clamps are made well too. Was $10 cheaper on amazon than it was at my local auto store for half the price. Holding 10psi of boost with ease. A++

It’s an adapter, that’s what I used it for.

Exactly what I needed for my 2003 Mini Cooper S! Very Happy with the quality and price 🙂

Was easy to install and all fitting was easy. Holds well and it’s been in place for several months with no issues.
