What's the best spark plugs can I buy for my 6 spd CL?
I'm doing the throttle body cleanup and decided to change the plugs. Car has 103K on it.

 

The OEM ones.... Do a search it's been asked a million times.

NGK part # 6994
IZFR6K11

 

I too am looking for new plugs and everyone at the pats store tells me NGK laser cut iridium plugs, those should work, right?

 

^ Laser Iridium

I noticed that Advance Auto Parts shows the wrong part number for the CL-S 6MT. The OEM plug is 6994 IZFR6K11

 

what a 2 step colder plug? i had the one step colder zex plug but destroyed one (dont know how)

 

lol cuz you literally beat the shit out of your car Tom......hahahaha

 

lol. u know how i do it. if it aint broke, dont fix it. so i try to break it and improve that broken piece/part. lol.

side note, ill be heading down to soutbend indian to the tire rack test track saturday, ill hit u up before i head out from my house.

 

NGK makes an OEM style plug and a Long Life style plug for the CLS. I emailed NGK to find out the difference cause they are both made of iridium and gapped the same. It seems the OEM nomenclature is a way to charge more. Advance has the Long Life kind. I bought those and will installed them soon.

I know there is another thread on there and people are pretty set in their OEM vs non OEM style so its really up to you.

 

so anyone know the number for a 2 step colder plug?

 

Would be a 7 or a 8 in ngk

 

Make sure you do the plugs last, AFTER the TB clean up, Sea Foam or whatever. Let the carbon get all over the old plugs, new ones will start off right that way.

 

I did seafoam twice before I pulled my old plugs and they were clean but still
