does anyone know if denso spark plugs make the check engine light come on? i went to the dealer today and the service advisor told me not to use after market plugs because they will miss fire and cause the check engine light come on.
as anyone had this problem or have any advice for me. i need to change my plugs real soon.
thanks.

 

Your service advisor doesn't know crap.

 

Actually this problem happened to me, i had aftermarket spark plugs and caused the engine to miss fire, my check engine light came on, so did my traction control light. I would recomend staying with the factory plugs the have a 100k mile warranty

 

how about the NGK Double Platinum??

 

That's BS!!


But I've heard that spark plug needs to be installed by professional because of tha gap.

 

Denso and NGK are both recommended by Honda. They come pregapped. If your engine misfired, then its because your didn't torque the plugs correctly.

 

or gap them properly or one was a bad plug. if i remember right we have a really small gap

 

I'm sure the gap is diff between the s and tlp do to compression diff.

 

anyone installed Bosch platinum +4? How is it? dooes it have any problems with gaps?

 

i have Bosch platinum +4, i wanna change mine back to the NGK because whenever i step on the gas padel the car feel like choking for like couple sec before start to move.

 

so, do denso plugs make a difference? will i feel any difference from the factory ngk plugs? or should i just stick with what the dealer gives me?

 

Denso IK16 will probably not make a difference since our platinum plugs are pretty good. If you have modifications like I/H/E then you should get colder plugs like IK20. other wise its a waste of money.
