NGK Spark Plug Comparison

[Skiwi]

Can anyone tell me what the difference is between the NGK BUH and the NGK BUHW?

I brought a 75hp 1975 Chrysler motor to use as a "parts bank" for my 75hp 1976 Chrysler. http://forums.iboats.com/showthread.php?t=447442

My existing motor had BUH plugs, the parts motor has BUHW, they are a lot newer and I was thinking of using them in my good motor, but want to check the compatibility 1st.

Thanks in advance

The "W" designation on the plug means the electrode is made from Tungsten.
Look on NGK's website your motor returned the BUHW plug. If the only difference in the "W" and non "W" plug is the tungsten, then I don't see why they wouldn't work. Cross check to be sure.

Hey Brewman, thanks for the reply

Anyone know if there is there some sort of advantage in using tungsten?
