Considering changing my spark plugs at the next service (early) after 5 years of the existing ones .
Done a search and checked the FAQ nowt!
Any one gone aftermarket and noticed an improvement if so what did you go with?

Does it make much difference? if so what?

i bought some from hardtopguy as way cheaper, do not think it really makes that much difference though

I used Splitfires on one of my old civics and they melted, id go with the Honda ones from hardtop guy.

I would use NGK Iridium or Denso Iridium (IK22 are standard heat range, IK24 are a step colder).

Thanks Chris any benefit to going to colder plugs other than longevity?

chrisr111

Depends if your S is standard or not.

Chris stock engine so I guess no benefit!?

for some reason I prefer the denso..

gapping the plugs when they are iridium is a real pain though.. and make sure they don't get loose.
