Which spark plugs should I get?

[mikey560]

I have a 98 srx 700 and I need to replace the spark plugs. I saw a few posts a long time ago about the best spark plug to get for the srx and now i cant find the post. So which spark plugs should i get?? I think the post i saw the person recommended the iridium spark plug because it doesnt foul as easy and last longer??

BR9ES, i think thats the plug. yami triples should never foul plugs or something is wrong

BR 9ECS plugs are for the SRX's,the BR9ES for the SXR's..

My 98 ran BR9ES, my 02 takes BR9ECS, must be a difference

If I remember right 1998 to 2000 was BR9ES 2001 and 2002 are BR9ECS there is a difference in the bottom if the plug ES is flat and ECS has a dish to it.

BR9ECS is supposed to help with denotation issues.I have ran the others without an issue,but staying with what is recommended..

My 98 600 ran the BR9ECS. Was the recommended plug no fouling. You can run the BR9ES in an emergency but I would stick with the ECS

The difference is about 8 bucks a plug! I guess they were supposed to limit detonation.

Don't buy the plugs from a dealer, shop around. I paid $5.50 a plug last year from a local chain of stores.

And only run NGK BR9ECS. Stock plug. As stated earlier you can run regular BR9's in a pinch, just don't make any top speed passes on the lake with prolonged WOT. Your pistons will thank you.

BR9ECS is what is supposed to be used, they hold their heat range better than regular plugs so you wont melt down or burn down on long full throttle pulls, i actually called NGK and asked what the difference was

I use BR9EYA. Same as the ECS, just a V end on it. (I think)

YIKES, does no one do top end runs with their SRX's here? I ran BR9EYA, and it melted a piston. BR9ECS is only way to go with on a SRX.

Royal wants $8.99 for the BR9ECS, partzilla is the cheapest I've found at $6.69

 

[roudyroy1]

I'll have to check out there again. I looked at the Fleet in Marshfield a few months ago and they didn't have the BR9ECS.
