I put BA pipeing from my airbox to throttle body on my EL Ghia, wreckers should have heaps by now, but you do have to stretch it a bit

Pipe is in! Fits like a charm. For anyone else wanting to fit an EL pipe into an EF Airbox, replace the last pipe (the one that joins to the box) with a 3" pipe 27cm long.

I'll post a pic soon.
