i stopped by my dealer today and all he had was br9ecs plugs....i know the 98 calls for br10ecs....but he said the 00-02 are running 9ecs's so it wont make that much of a diff....i bought the 9's do u ppl think they will hurt my srx?
I would run the 9s...that all we ran in our 98 and 99 SRX's
I have always run the br9ecs in just about all my yamaha's. Should be fine.

Darn it. I already bought the BR10ECS plugs because I went by the manual, which I guess was not updated. Will it have any negative effect? I'm more interested in reliability and not having major engine problems as opposed to squeezing every ounce of performance. If it's going to cause me grief I guess I'll have to scrap them and buy the BR9ECS. I've tried to get a clear explanation of the difference between the two but had no luck so far. I know that some are called hotter or colder plugs, but I don't understand what that means in practical terms. Thanks for any advice guys.

So it would be alright to run BR9ECS in a stock Viper? Are there any advantages to doing so? Thanks.
The diff in the 9 vs 10 is that the 10 is rated at a colder heat range meaning that it is meant to be used in what I would say late spring or summer temps and by that I mean warm weather.The 9's were in fact superseded in place of the 10's which came in the 98's and as it turned out were too cold a plug and fouled frequently.Run the BR9ECS plugs and don't worry about it,anyone who has/had an SRX no matter what year ran them and they work great.
As far a running them in a Viper I can't really see too much advantage over the stock plugs (BR9ES correct?) other than the ECS is touted as being less prone to fouling.Plus the ES' are about $4-5 a plug cheaper but I don't see any reason that they wouldn't work alright.

the ecs vs es one is a double electrode plug and the es is a single i would just run a hotter single electrode plug (9-es) i alway run 9's in everything dirtbikes sleds quads ect... i did run the 10's last year because of the book and lost a position in the snow drags in wells nv because of the fouling problem i switched and haven't fouled one sice ... with good maint... good luck

the br9ecs plugs are factory gapped for srx and should not be adjusted

The 9 vs. 10 thing is not what temps outside it can be run but at what heat range it is designed for inside the engine. It is the rating at which the plug can remove heat from the combustion area.
