CR9EIX SPARK PLUGS

[MSRX-ERNIE]

Have any one of you tried NGK CR9EIX spark plugs with Iridium center electrode on your RX sled?

Thanks

 

[jtssrx]

yes . My sled started 100 percent easier with them. they are awsome

I also use them but Freddie did have a slight power increase with the NGK cr10ek's. I myself like the benefits that Iridium brings to the table.

I run them in my 03 shorty LE too. No problems yet..............

Budda,
Jim put in new plugs when I bought mine from Doc. 1 1/2 seeasons with no problems. That's with stock plugs that work 3 times better than other plugs. Starts 1.5 times better than other plugs, and my back doesn't hurt when running stock plugs.

P.S. My love life is better with stock plugs also.

I ran those plugs all last season with no problems.Didn't notice any gains in power,ease of starting etc .Most noticable difference was the price!

They make absolutely no more power than the stock sparkplugs and less than the CR10EK's but I could see a cold start up benefit from any new plug versus old.

My machine ran cleaner as well.

CR9 means that the spark properties are the same. The different material used for the plugs just makes it last longer.
