I have a 1986 F150 with the 5.0L V8, 4 speed and i was wondering if anyone had ever replaced their old air box with a new intake set up using an intake pipe straight from the throttle body to a 'performance' air filter. I ask because i am doing just this, but my problem is that the throttle body has 2 pipes to the air box that are both 2 1/4 inches in diameter and the smallest filter/intake piping set up available is 3" in diameter. So, any ideas on how to merge both 2 1/4" pipes into one 3" pipe? Ive done a lot of looking for Y styled pipes, but none of them either fit or are intended for exhaust and as a result cost about 80$.
The only cost effective idea i have had so far is to cut the old intake pipes about a foot out from the throttle body, and shave an angular piece off the end of them then use some heat proof tape/gasket maker to seal them together and fit them into a coupling that will then attach them to a 3" tube that will run to my filter.
It seems to me like this would work quite well considering it sounds like a rube goldberg special, but any advice is appreciated
