NexRex · 03-21-2008, 04:32 PM

OK Ive read the sticky on spark plugs but am looking for some end user feedback.. about to get my stageII setup installed and tuned ,Im alreadey due for new plugs (75k) wondering if I should stick with the stockers or go to the 1 step colder plugs?

Setup

Magnaflow exhaust

Nothings installed yet and going to probably do my plugs this weekend. stockers or step colder? can I run the step colder for a week or so without mods until I get everything in? any help appreciated

for those mods, stock plugs should be ok.

I've been running 1-step colder double platinum for the last 30k miles or so with 0 problems...ran them in 100 degree temps and 0 degree temps. The idle is alot smoother I think and the car runs fantastic...typical stage 2 but fully tuned 17.5 psi right now.

When I went stg 2 in my old car with one step colder plugs, the car didn't run very smooth sometimes. It randomly misfired. With stock plugs it was much better.

When I custom tuned my stage 2 map and starting running more boost and more agressive timing I switched to 1 range colder. Also gapped to .028 instead of .030. Car runs strong as hell! Ran a 13.1@103 today.

I running well over 300whp with stock, some people dont like to use colded plugs, ask your tuner what he likes to tune with

I have NGK iridiums in my stock WRX. runs fine. i think you'll be ok with them.

There was a test done recently, the article is in Import Tuner magazine regarding the testing results of stock copper plugs, platinum plugs, and iridium plugs. To the skeptics, the iridium plugs actually showed quite an improvement over stock or platinum plugs, so I don't see how there can be any argument against them...other than the fine tips that can tend to snap off if you're not careful. You will be fine with the 1-step colder plugs, give it a shot but stick with NGK the Denso plugs are junk.

not really pertinent to the conversation but ok

Why are Denso's junk? Ran Denso's in my commuter car (Acura Integra) for nearly 80K and they still look and perform brand new.

Sorry, just personal experience with them, that's all. I'm sure there are plenty of people that have not had any issues with Denso plugs, but I had to replace 4 sets of them in a matter of 2 months on the Nissan I had, the electrodes kept snapping off for no reason.
