I was told i need to replace my spark plugs by the mechanic at the local dealership since i have over 30,000 miles. Any suggestions?

 

How's your car configured? Stock, s2...?

If stock to stage 2 you could just use ngk v-powers. they go for like 12$ a set at the dealer (yes the dealer should have these) They will give you a little better spark than the champions...but I would replace them sooner than 30,000 miles. As I would any standard plug in this car.( I go like 9000 miles max, myself. If you do NGK iridiums you can get a bitcloser to your mileage. Best plug is probably the denso iridium, but they aren't cheap.

Also, if you haven't already, get wires, too - you will like.

 

I put densos in at 12,000. I have been happy so far.

 

denso's are definetly the way to go imo. i've tried the champions, the ngk's, and now the denso's. the irridiums are just a much better plug overall. smoother idle, smoother acceleration, no break up at all. i couldn't be happier. yes, they're a little pricey, but worth it to me. well, not even really that expensive, $50 for a set of wires, $12 for a set of plugs. i was changing my ngk's every 6k or so where i can get 30k from the denso's. so it's cheaper for me in the long run....

 

You cant go wrong with what you read here so far...

 

I'd say the NGK's... but I'm biased on plugs and wires...

I'm surprised the Champions lasted that long though...

 

densos rock.

 

I replaced the wires at 13,000 when i bought the S1with MSD. Ive been spending so much time working on my GSR that ive payed little to no attention to the SRT. Ive been changing the oil at 3,000 but thats about it.

Thanks.
