Do you recomended me good spark plugs on my turbo setup (ca 400PS).

Must I use one step colder spark plugs or normal? I drive only in sommer.

And which brand? NGK or DENSO?

Many thanks

Martin

PS: sorry for my english, i know, she is sux :-)

 

anybody?

I want buy IK24 one step colder. But i dont know, if they are good for my setup.

 

I drive only in summer, fuel 95 / 100 octane.

 

I am using the NGK bkr7e, they have worked well and I hear a lot of people are using them. Plus they only cost about $2.00 a plug.

 

This question gets asked several times a week.

I currently run bkr7e's but I think we need a definitive answer and get it stickied as you are going to get about 7 or 8 differnet answers here.

 

Yes i found many threads about spark plugs, but a few about spark plugs on turbocharger.

Do you use BRK7 on turbocharger?

I bought IK24 one step colder from DENSO, i dont know, if they will be good.

 

NGK
BKR7E = one step colder its what I run. If you run over 400whp I would suggest 2 steps colder and over 500 or so I'd suggest 3 steps colder.

I can confirm many tuners supporting this plug including Shawn Church.

NO IRIDIUM in the turbo car FTW. You'd be safe on a BKR7E. (yes they are pre-gapped but still gap down accordingly, .028 or maybe down to 25 to be extra safe. It's dependent on too many things to be able to just state the answer. Learn how to read a plug if you don't fully understand already.

I never run plugs longer then an oil change.... (mobil 1 10w-30 for 3000 miles)

You can change plugs as often as 1000 miles depending on your tune etc. I think they're ok up to 3000 on my car in general.

why no iridium?
