Ms3 Stock Spark Plugs

[funkyman]

Here are close ups and part number of the MS3 spark plugs in my oppinion this is top of the line Iridium made in Japan and certainly does not need any upgrade whatsoever.
Additionally,the service manager said that at one point there was an internal memorandum on after market spark plugs not being compatible or rather having compatibility issues with various Mazda models ,including the 3 series since the 2.3 liter engine is identicle.(headbang)

Interesting, that is one stage colder than what comes stock on a lightning. Ive been using copper NGK BR7EFs on the truck. I had 1 set of Denso Iridium and would crack real easy on the big V8 so i went copper. NGK plugs are really strong, unlike the Densos

I would venture to say for the MS3, one step colder with excess of 20+ psi would be a safe and wise move. Just need to find an equil of the BR7 in Iridium. Thanks for the info (boobs)
