Hi all, well I've recently bought an '87 TII. I got it for relatively cheap. The car has 60,000 miles on it, and the exterior and interior are in excellent shape. The car sat in a garage for the past 4 years though, and in that time the engine siezed. Right now, I've got ATF sitting in it, and am hoping that I can break it free tomorrow.
Anyway, as I'll be replacing all the filters, I decided I might as well buy a cold air intake, rather than buy a new filter for the crap air box. I found that HKS has a CAI for the car, but I couldn't find any pictures of it installed in the car. I found some others, but HKS seemed to be the best brand. I looked around on the forum about it, but most of what I found was more related to jerry rigging, and I'm not much into that at this point in time. So, could anyone point me in the direction of a good CAI? I've read that just replacing the air box w/ a cone/mushroom type filter at the end of the TID doesn't really do any good since instead of restricting airflow, you're just sucking in hot air. Do any relatively inexpensive aftermarket kits do a good job of reloacating the intake to a cooler location, or is that something that you pretty much have to do yourself?
Thanks for your time.

Well, first... welcome to the forum... congrats on finding a turbo rx-7
Secondly, if you want a 'real' cold air intake on your FC (2nd gen Rx-7) your going to need to build one yourself, that or design or buy a cold air box for your filter to sit into. I've seen alot of people have great luck with cutting a three inch whole near their radiator, running an extention pipe from the AMF than mounting the air filter where the coolant overflow bottle is. I'm not sure of the HP gains (if any) but this would be my best guess for a cold air spot.

all i'm gonna do is pull the little black box and drop a cool colored Auto Zone Cone on it and get the little attachment from ebay and keep the passanger FTP lens out (even though i hear it doesn't really help much) but i could how ever use and opinion as to take out the vent thingy ontop of the fan shroud... i dont think i should because air is desinded to come from there so i think i'm gonna keep that ontop of the shroud

Jay Jay, instead of getting the adapter and filter separate, just get the hot air intake on ebay for $10.00 (cone filter + adapter).. I'd keep the air duct on the shroud.. some outside air is better than none.
