So I gutted my airbox and put in a Spectre high flow reusable air filter alright? Well my car was perfectly fine until I replaced all my spark plugs with NGK Iridium core plugs. After that my car started knocking a little bit at idle. Well it's just at idle and if I give it a little gas it stops and it never comes back until I shut the car off and start it back.
Is it possible with the better spark plugs and higher air flow the air:fuel ratio is off? If s can I tune it or something?

Re: Spark Knock?
Did you replace the spark plug wires? Nothing you did to the intake is causing that much of a change to necessitate a tune. The PCM can compensate for it.
