Hello everyone, I'm looking to upgrade performance a little bit and am trying to find a cold air intake conversion for my 1990 L98 Corvette. I see only K&N replacement filters with an optional cutout top to help reduce air restriction, but no cold air intake kits. I did see some for the LT1 engine, but I'm coming up short for the L98. Any suggestions or leads? Are the K&N direct fit replacements any good?
