As for any oiled air filter, no. Putting an oiled air filter in the air stream ahead of the MAF is asking from problems down the road. While they may sound cool, any power improvement is at best within the margin of error on a dyno pull, and every GT 2, GT 3, and Cup race car out there runs a dry element air filter.

That's why I haven't put the K&N filter back on again, I've been reading a lot of horror stories about oiled filters on these cars. I was looking at the BMC, but it's also an oiled filter.
