I was woundering does anyone make a intake and filter. on jc whitteny they only have them for 88 and up i got an 87. will it fit? and also what about throttle body spacers do those really help or should i lookat injector upgrades? i just want some simple bolt on power things.

I put a spacer on my 89 a couple of years back and it seems that it made a little bit more power, especially at low RPM.
Whatever you do, do not buy the Pacesetter Air F/X intake for your truck. It is a POS and you will be sorry you wasted your money. I bought one and ended up ditching it in a month.
if you intake is set up the way i think it is, it runs from the cleaner to the fender in the order 1. element housing 2. flex tubing 3. air canister 4. fender what i did to my 89 when i had it was replace the canister with a section of 4" pipe (abs or pvc) and a fernco fitting and a couple of hose clamps. This got me from the fender to the element housing in one staright shot. for the filter just get a k&n and be happy [img]/ubbthreads/images/graemlins/smile.gif[/img]
I have a 90 gmc put a tbi spacer but before install i cut 2 1 in each chamber angle grove from upper in to bottom out apx 1/6 wide 1/16 deep that gave alot of torgue over just spacer also the deepest k&n filter tounnel directly to the cowl hood scope , the ari wont matter as much at low rpm also an MSD system wires heeders then 488 gears stronger tranny bands strong joints ahhhhhhh !!!!!!! then your broke
