As stated by others, the engine series. The F-series was the previous Accord I4, the H series was essentially a DOHC head on an F series block, etc. etc. Every manufacturer has their own codes, Nissan has the old school VG series V6's that were bulletproof and the much renowned but a little long in the tooth VQ series V6's.ok. whats the K stand for?
A resonator doesn't restrict very much, naturally it doesnt really induce that much back pressure.I am not an expert on this but I do remember reading a thread stating that removing some of the back pressure on the I4 will reduce low-end power. Again, I am not stating this- I am asking this. True?
Or was I lied to like a Chevy dealer tells you "It should last for years."?
