Cold Air Intake for 87's

I have a K@N in my stock intake box, what is everyone else running? I couldn't find many choices out there, is there any mods for the stock box as well?

The " cut lid" mod where all the louvers are removed from the cover exposing all of the filter element to incoming air flow

Other option is the aftermarket setup that picks up cold air from inside of the radiator shroud

Requires cutting a hole in shroud.

Yea... such lame aftermarket options for us here. There are really only two options left, that strange one from SLP (which is ridiculously overpriced) and the Vortex. I've never heard anything good quality-wise on either. I had been running the cut stock lid but definitely want a better piece to take advantage of the ram scoop.

A few guys are running C5 intakes on engine swaps with little modification. I'm going to try it a C5 air bridge this winter and cut the radiator shroud for a bigger filter. If it doesn't fit to my liking, going to just build it.

I put on a SLP PERFORMANCE cold air package,part #21050 cost $149.95.replaces stock air filter but has a section that feeds thru the radiator shroud and picks up cold air from there.
still looks stock but it works really well.
as you say there is not much out there for C4 that look good.
the only one i like is the 3 pronged one for C5 but your still sucking in hot air from engine compartment.

I like the SLP option, but how good does the cut louver option work and is it worth it?
