Denso or Champion

[danyz250f]

Which would be better to use, I currently have the spark plug options of: denso W20EXR-U11(little bit fried on top or champion RN9YC

None of those 2. Get NGK.

NGK fo sho

 

[Chaddycakes21]

^^^^ I agree. they have been proven and are highly popular with DSMS

 

[Maverick3169]

NGK is what I always use for my DSM. Stick with what works.

Def. NGK. I got a set of dual tip at summit racing that are tight. We sell Champion at Drug Mart....

 

[Crimsin]

I wouldnt put champions in a Honda

 

[eclipsegsx1736]

The general consensus here is to use NGK BPR6ES for a mostly stock car, and BPR7ES for a more modified DSM. Run .030 gap if you're boosting 18 or so psi or less, and .028 if more.

Sucky ### thats all the parts stores had. I will have them order some new plugs. So I have a slightly modded car so should I get the ngk 7 s or the 6 s and which one is colder.

I replaced my plugs today, and what did I find, champions, I put some NGK platinums and it runs way better. Champions suck

I would go with the NGK BPR7ESs because you are slightly modded, and like eclipsegsx1736 said gap them .030.

I have not done much to my car yet, I bought them cause thats all I could find at the time, they are still better than champion
