tbi 5.7 air filter box

[eran tomer]

i have a k&n open filter and i wanna go back to stock air cleaner.
my filter has only one stud although it's a 95.
is it possible to install the 2 stud box without changing the tbi itself?

yes,

the nuts that attach the air cleaner studs/ hold down the TBI unit are what is different. You'd have to look at your current setup and see if 2/3 of the TBI nuts are threaded (would be the 2 across from one another). If they are then all you would need is the other air cleaner stud and the correct 2 stud lid.

the dual air cleaner studs are threaded into the 2 rear tbi bolts?

yes

do later models have the air duct inside the right fender or was it discontinued?

My 1997 C1500 vortec 5.7 has it

my 95 had the duct, i still have it in my garage along with the air box too

I have a heavy gage mesh just before the filter on the intake duct, to keep the mice at bay. For me an open K&N would be destroyed. All Good.
