Filter size

[ontuy]

Sorry for such a basic question but my car is inaccessible for the day and I wanted to order a cone filter for it today. I intend to just put it on the end of the MAF sensor but need to know if it is 3" or 4".

Thanks

Get a 4" filter and a rubber reducer from the Home Depot/Lowes plumbing department.

Based on my other reading i would agree. 4" it is.

Thanks!

Or get a silicone adapter from some online retailer.

I only use those plumbing parts for my custom center console toilet.

If it can survive on my 608hp Trans Am, I think it can survive on a GTP with half the hp.
