DemonGT · 04-27-2001, 11:24 AM

im going to be geting a cobra intake some time soon...i was wondering if the intake plenum spacers are worth the money and would it help me much? i figure if i have the intake off puting a new one on that be the best time to put one on..and if they do help and are worth it what size? 3/8 or 1"? and would it clear the stock hood?

The 3/8" spacer does fit with the Cobra upper under the stock hood, my dad runs one on his 93.

I run the 1" on mine and it keeps the upper 75-100 degrees cooler I have tested it to see how much difference it makes. The longer runner do take a way you top end a little it may make you peak at 200 rpms earlier then normal, no big deal when your turning 6300 anyway.
