ifr8h11 ngk or vk24prz11 denso
That NGK ifr8-h11 cost me 39 USD, can I put some cheaper spark on my 450?
Can I put spark from Honda CR 2 stroke, NGK B type; BR8EG and similar?
CRF 450 spark size?
i would not put any other plug in myself they seem to last for ever. i would shop around that sounds too high.
Here is a good link that brakes down the numbers and letters pretty well : http://www.spark-plugs.co.uk/pages/technical/ngkjpg.htm
I run the NGK IFR8H11 plug in my 05 and never had a problem with it. It also came with a two year warranty so I bought two of them and swap them out once a year just for the hell of it.
Napa autoparts has those in their system. I paid $18CAD. Cam.
