Spark plugs - non O.E.?

5036 Views 13 Replies 10 Participants Last post by  srmarti
Has anyone experimented with non-OE (i.e. non-Iridium) plugs in our ICEs?

It has been a long standing argument among the VW community (cars in the 2000s and newer generations) that you get (significantly?) better fuel economy with Copper plugs over Iridium at the cost of the plugs wearing out 2-3x faster.

At present I drive a lot of ICE miles, so I'd be willing to Guinea pig myself if I can determine what plugs are "compatible"

Oh yes,, A spark in a gap is not just a spark in a gap. It matters what metals the spark is between.:rolleyes:

When I was younger I bought a J.C. Whitney GAS SNAKE !
You drop it in the gas tank and it consumed impurities in the gas and resulted in 110% (significantly?) better fuel economy.
It was not fun having my tank over flow...:(
