Colder plugs in the MS3, whose using them?

[shane02pro5]

So Mazda specifically calls out Iridium plugs? I have always read that Iridium plugs were bad for turbo engines due to getting hotspots and causing pre-ignition!?

I've had the 1 stg colder plugs in for over 6 months and have set them at 2 different gaps
studdering is still present
the colder plug isn;t a bad idea when heavy modding but I can assure you they are not the studdering cure

I dont think they will fix that. I just wanted make sure the car still ran right and no spark blow out or anything.

What plugs did you go with?

Also, I'm dynoing my car on the 26th and was thinking about a BCD and MBC combo, set to 17psi. Given what I already have done to my car what's your take/how safe is it?

Don`t touch the factory originals they are goog enough.

I don't think they are considering our mods. I think they might haved crakced or something when I upped the boost.... I never had this sputtering problem during idle...???

I went with one stg colder ngks. Ptp has them on the website. He sent me a set of stock heat range ngks and 1 step colder. Im gonna try both and see how it runs.

your car should be fine with those mods. If it cuts then turn boost down a bit. Thats the exact setup I went 12.7 on. What are your temps where you live right now?

Stock ones are good yes but Im not gonna take the risk of them breaking or fouling. Plugs are cheap and I like to change them often.

What are your temps where you live right now?

Today it's 60 degrees (extremely rare) but, it's going to drop back down into the 30's and 40's (normal temps). I'm beginning to think that my issue is weather related because I have not had experienced it for the last 3 days, temps have been around 65-70.

What BCD and MBC are you using?

Any issues to speak of?

Im using a map clamp instead of the bcd. If you are good with wiring then runa map clamp. Otherwise order the atp bcd and a turbosmart boost controller or forge bc. both are good.

Did it end that problem after 5,000 rpm that people called a "misfire", or does it just feel good on the butt dyno because it's a new set of plugs?

 

[shaodome]

Stuttering and sputtering are different than hesitation from fuel pressure drop. I had both of these problems and the stuttering/sputtering went away after i replaced the stock spark plugs. Two were cracked. I still have the hesitation from fuel pressure drops.

BTW, these spark plugs are not cheap and definitely not $10-$15 dollars each. I paid $85 for a set of 4 from the dealer and that was with a valued customer discount.

You are at stock boost with just a few bolt ons and cracked plugs? What the hell!

 

[Davidb]

how did the old plugs look?

 

[mrlilguy157]

driver311, update mannnnn

 

[driver311]

NGK LTR7IX-11 is the plug I went with. Car is running great with no hiccups. Didnt cure anything to crazy. But car still runs good with a colder plug, which i think is a good sign. Ill know in the next few days about some more dyno info for you guys.
