I Need To Buy New Spark Plugs For My Cls What Brand Do You Recommend?

 

I am glad you asked this question because i am do for some new ones and was going to post this exact post!!! i lot of people use Iridium Sparks but I wanna hear other suggestions as well as suggestions for spark plug wires!!!

 

i just got sparks and wires from the dealership (free warranty) what kind do they use?

 

Denso Iridium Is the only way to go... I belive I got the IK20. Search on here for the correct ones. I just bought what everyone said was the best one.

I thought we didnt have wires, thought we had coils?

 

NGK Iridium IX.

Our cars don't have spark plug wires, if the dealer sold some to you, you got ripped.

 

My bad "ignition wires" not spark plug wires I kinda thought they were the same thing sue me, and as I said they were free

 

they don't have ignition wires either. they have coilpacks. i only use ngk plugs.

 

this is a second gen forum I have a first gen

 

 

I prefer the oem NGK over the densos. they last longer


J32-A1
NGK- PZFR5E-11
DENSO- PKJ16CR-L11


J32-A2
NGK- PZFR6E-11
DENSO- PKJ20CR-M11

 

Bosch Platinum Plus - $2.99 at Autozone. Just replaced them at 90,000 and the car's running like a champ.

Plus, I think I gained 20 RWHP

 

There is no way you gained that much power!!! And the CL is not RWD. But when I need to upgrade my sparks i am goin with nothin but bosch baby!!

 

take it easy there champ i think he was kidding

 

Word.

 

HA! Ignorance is bliss...

 

I heard Bosch plugs was a bad no no on these engine's. Thats why I went with the denso's. Granted they are 12.99 each but you can get them cheaper on ebay.

 

Yeah, I've read that too...what source is that coming from? I think it's complete BS, but pretty funny as well. I actually read somewhere that since Bosch is German, they're not meant for a Japanese engine For a NA CL type S, Bosch plat plugs are fine. They lack the BLING factor of the NKG's and Denso's, but they're a perfectly reliable (and inexpensive) platinum plug.

Take 2 identical CLS's and put Bosch plats in one and NKG/Denso Iridiums in the other and I guarantee a difference wouldn't be seen or felt (although I do agree that Iridium is a very promising technology, but it's probably not truly realized in our J-series engines). But some people are willing to spend a lot more for a possible 0.00001% bump in performance and bragging rights, which is all good!!

Oh, and I should also add that those Split-fire plugs iz da shiznits!!! Twice the spark = mad HP!!!

 

i won't buy plugs from a company that runs a gimmick with multiple ground electrodes.

 

Point taken. But all companies have marketing departments that use gimmicks to bump performance numbers (i.e UR pulleys adding 20+ to a Honda Accord...PA LEEZE), etc., but that doesn't mean their products are poor quality or don't create results . The Bosch 2 and 4 ground plats probably do have benefits, but none that anyone here is likely to see or feel.

Damn, I sound like a PR guy for Bosch...but you get the point.

 

I didnt know you were just kiddin sorry killer!! When I need spark plugs I will do the research myself and get the ones that I think will suit the CL best, but good info on the bosch plugs were not good for the engine.

 

Added Honda P/N for Type-S engine NGK plugs.....they are 13.63 ea at acuraoemparts.com (Delray Acura)
