Morning chaps,

I've always used NGK plugs in my bike (F4i) but recently found I can get the Densos for about 20% less.

Anybody running the denso plugs in their bike atm, not looking for them to work better than the NGK and I am not looking for or expecting power gains, just want them to work as well as the NGK plugs that I trust.

Plugs are


NGK IMR9A-9h

or

DENSO IUH27D


Any thoughts or other plugs to consider?


Thanks

 

I just put a new set of the NGKs in, what I always run and love them!

I'm a fan of the E3's I put in my bike. Had them in for 6 months and noticed a difference. Only downside is you gotta modify the spark plug wrench cause they are a little taller.

 

As long as they are the same composition and heat range they should be the same. I have used both and found no difference.
Thank you,
David.
