hands down what is the best spark plug to get? i drive 100 round trip in my 98 a4 2.8 quad. changing this weekend gas mileage gone to nothing.

 

bosch plat..


unless u have major mods?

 

i was think about useing the new bosch








Bosch Spark Plug

Spark Plug: Platinum IR Fusionwhat do you think?

 

i just got ngk iridium ix

$6 a pop

 

I've heard some good things about copper plugs. Anybody that has them care to review?

 

not too familiar w/ copper plugs...
but ive ran Denso iridium / colder plugs
really not needed unless ur have some mods.
what engine mods are u running?


if none -Id go w/ factry recomended.. NGK / Bosch plats etc...

 

I know you have a 30v, but many 12v guys are running delco rapidfire 9s. They're about $4 each and work great.

 

think i'm going to get the ngk plug turbo was talking about. unless anyone has a really good reason why not.

 

For a 2.8 I wouldnt bother with copper. Just get some plats or whatever will last a long time.
copper is obviously the best conductor of electricity and will disipate heat the best, so they are ideal especially for forced induction engines due to all that hot compreesed air blowing by them but they need changed pretty often. I wouldnt want to change plugs on a 2.8 every 10k-15k miles.

Yeah plugs choice isn't that important in non-FI engines. It's the gap and frequency of replacement that's important.
