So I installed my eK&N SRI a couple weeks ago and so far so good, no CEL. The pipe and fittings are a $50 setup from eBay and I bought a genuine K&N filter, which came with a sticker so the setup looks legit!
My thought is that the car doesn't know if there's a $50 or $300 piece of metal tube attached to the throttle body--it's the filter that counts. No gains in power obviously, but it sounds awesome, especially as vtec kicks in.
Oh, and the dealer I bought the car from had claimed to change the oil and filters, but strangely, the air filter I pulled out appeared to be the original!
