Funny you should ask
These are best:
Maintenance Part: Iridium spark plug OE manufacturer (NGK), 2004-2008 Acura TSX CL9 - HeelToe Automotive
I just did mine at 100000 miles and I would say DO NOT WAIT to change them. I must have gained 5hp with new plugs and a K&N drop-in! I am so amped about it I came up with a completely new maintenance schedule for my car. Announcing it soon in the forums here.
I've always heard the Lasers are the best replacementWhich NGK iridium plug is the OE replacement?
NGK's website has Iridium IX and Laser Iridium?
Did you notice an improvement at all?
