I've always believed in replacing spark plugs with what came in it from the factory. I'm not a fan of changing brands just because their marekting campaign says I need to. I learned this the hard way. I put Autolite's into my Dodge (uses Champions) and blew my head gasket a few months later. I still say they were partially related... But back to my question...

 

I'm planning on doing plugs and wires next weekend on my 01 OBW and was wondering if the NGK "premium" plugs are really worth the extra $$$, or should I stick with the V-Power plugs...

 

Here's the specifics on the car, Just over 85k, New Air Filter, NO CEL codes, etc, and having lots of "gas guzzling" trouble. Only getting about 20 MPG. Was doing much better before and hoping that by changing the plugs (changed @ 60k) and wires (original) will help. I've got OEM wires on order with SubieGal, and plan on getting the NGK's at the local NAPA.

 

Thanks in advance to all who reply...

The only real benefit of platinum or other precious metal plugs is that they last longer. Given how easy it is to change the plugs, I prefer the v-power myself.

replaced the plus and wires today... It was a great day almost 60 degees...

 

got my OEM wires yesterday... THANKS SUBIEGAL

 

used the V-Power plugs, the one's that I pulled out were kinda oily on the rim of the threads. Spark area looked normally worn...

 

Didn't realize how deep in the plugs were on this one... Only changed a set on my 2.2 a few years ago. Was kinda tight on the driver's side, but worked thru it... Passenger side was far easier once I removed the air filter stuff...

 

We'll see how the gas mileage fairs, seems to run better. Hopefully it was the answer...

Sometime yes ...sometimes no. Example: the iridiums with the full-size center electrodes are rated at 100k miles, but if you read closely the manufacturers sites you'll see that the fine-electrode iridiums are rated at 30k miles - same as a standard plug. In this case the advantage is lower ionization voltage (easier firing) and less mixture shrouding.

 

**** ***A**!
