Spark plugs?

Recommended Posts

Hi all

Whats the difference between Standard Resistance and Iridium spark plugs? Should i run a NGK CR8EIX Iridium in a 08 Husky TE 450, or stick with the good old NGK CR8EB???

Thanks in advance

I'm not sure what the difference in function is but I know irridium spark plugs are alot more expensive. If what you have now works fine then just stick with it.

Only difference are the tips, iridium won't give you better performance (more a placebo effect) but what it will give is a longer life as the tips don't corrode away like the copper plugs, according to NGK spiel will last over 100K miles:unsure:

Personally, if you own a 2 banger go the standard plug as fouling is more common. Own a 4banger EFI, your choice as when was the last time you fouled a plug on an EFI 4 banger? PS. My FE350 comes with an iridium standard, have std plug as a spare.

Good info thanks omg. Ive only changed the plug once in 8 years, and its still fine, so ill go the standard. Thanks for the reply.

I asked this question of the mechanic that does all the servicing of our work cars and he said there was no advantage in using the irridium plugs in a dirt bike.Apparently they were first designed for cars where access to the plugs was difficult and therefore expensive as already mentioned they last much longer but offer no performance increase.
