NGK Racing Spark Plugs

[mac013]

I know spark plug topics have been covered on here numerous times and the concensus seems to be to use NGK CR10EK's. Question is this, I managed to get my hands on a set of NGK Racing plugs # R0373A-10. Can these plugs be used on the Nytro and should I be using racing plugs in this motor? Thanks

I would say your best bet is to ask NGK, they will know.

According to the cross reference in this document: http://www.ngksparkplugs.com/images/pdf ... atalog.pdf -- they are used in place of CR9E.


Here's their official write-up: http://www.ngksparkplugs.com/products/racing/racing.asp

My theory is that there is nothing special about their "racing" plugs. Just a different part number on it to make racers feel like they got something special at 10x the price. Which basically means that you got yourself a box of... probably CR9EIX.

Thanks for the help. Basically what I can determine is that these racing plugs are built to a better standard according to NGK. These plugs are made from expensive materials which include platinum and iridium. NGK web site says they are for high performance engines with high compression. Sounds like they will work on the NYTRO and are a replacement for the CR9's which the NYTRO uses. So I figure I should be OK using these plugs. I wouldn't spend the $100 a plug but I have them now so I probably will give them a try.
