Is there any Sparks plugs DIY for 03 CLS on board?

Thanks a lot..

 

There doesn't seem to be one. However I have recently replaced my plugs so let me see if I can help.

-Remove engine cover. Four bolts, unscrew then take off plastic cover.

-For the front plugs you just need to remove the coil packs, One hex or torx screw on each. Remove screw then pull coil pack straight up they are kinda tight fyi.

-Drop your spark plug socket with extension down the open hole and break loose the old plugs. They should stay in the socket and come out easily when loose.

-Put new plug in socket then lower into the hole. Make sure you get the plug to sit evenly before you try to tighten it. You can tell by seeing if your socket is leaning to one side should be straight. Plus you can sort of feel for it. Tighten until the ratchet stops then give it a quarter turn to snug down the plug. Thats it do not over tighten or your fucked!

-Now replace coil pack by pushing down till it makes a seal on the top of the valve cover. Now for the rear plugs.

-I recommend removing the strut tower bar to give you more access to the rear plugs. Its doable without, but removing will give your hands more room to work.

-The ends of the strut tower bar have a few bolts on each side can't remember how many. Remove those, then pop of the two covers on the black plastic wiper cowl just below the windshield. Once those are removed you will see the other bolts holding the "back" of the strut bar in place.

-Now you can lean your whole body over the bumper/engine to get a good look and grip on the rear coil packs. I found that using a u-joint on my ratchet helped alot.

-Now remove coil packs and plugs like on the front and replace with your new plugs.

-Replace strut bar (if you removed it) engine cover and your done.

Someone chime in if I forgot something, going on pure memory right now.
Hope this helps and good luck. Do it yourself whenever you can!

 

^ looks good to me. Its exactly what I did when I swapped mine. It was pretty straight forward

 

what are some good spark plugs that would be good to use? also I heard if you point the spark plug a certain way you get some extra hp. Is this true?

 

Use the original NGK's...........OEM for a reason

 

wats the recommended time to change them at

 

^ The OEM NGK's should be changed at 105K. They're pretty pricey so you better start saving lol

 

well Denso and NGK are the main contenders for spark plugs. you made me look some stuff up because im thinking of switching mine out now too lol

You gotta search for good deals man lol Ive found some Denso Irridium plugs (supposedly the best) for $10 each online...so $60 for the set taint too bad.

Unless youre talking about those "Pulstar Plugs" lol i think those may be the biggest scam on the market...something like $25-30 per plug?

 

^ Yea $60 IS a lot. There's plugs out there for like $2 ea. So $10 a plug is pricey

 

im sure you can find $2 spark plugs for a Geo or Suzuki but seriously how is $60 alot for spark plugs for a car that original sticker price was $30k? lol

 

Check EBAY item 170203588208

 

If I had the money to afford a $30K car then no, I wouldn't think its expensive. But I can't, so yea it seems pricey to me. That being said I'm not to cheap to buy the things that the car needs because I knew that certain things on these car are expensive

 

original plugs are called NGK Lazer Iridium spark plugs or NGK Lazer Platnium spark plugs. The platnium ones were used on the 01s. Plan to use these plugs if you dont want to change them out again for another 105k. A common plugs used on this forum is NGK irdiums but i wouldnt run them to 210k.

 

OEM

Platinums for 5AT

Iridiums for 6MT

 

Don't forget to apply some anti-seize compund to the threads before you install the new plugs.

 

so the best ones for the 6 speed are the iridium ngk's?

 

 

The way i see it, yes. They're OE in the 6MT for a reason

Unless anyone knows of a plug that will work better?

 

i dont.
but you can use the lazer iridiums in place of the lazer platniums right? IE: my 01 CL-S

 

Here knock urself out in deciding
(these are based off the 2003 CL Type-S [Auto])
Denso:

Std Plug: KJ16CR-L11
Dbl Plat: PKJ16CR-L11
IR Long: SKJ16CR-L11

NGK:

OE Lazer Iridium: IZFR6K11

 

^ I dont know where you got that but this is straight from the service manual:

J32A1----------NGK PZFR5F-11
Denso PKJ16CR-L11

J32A2----------NGK PZFR6F-11
Denso PKJ20CR-M11

But it does not specify one for the 6MT

 

The 6MT and Auto both use the same plug.

 

what size socket do you guys use for the plugs?

 

okay, if you guys are having trouble, just go to the NGK site and check. im pretty sure running iridiums in place of platniums will not cause any negatiive side effects. the J32A2 used in the 01s are the same as the 03s, auto or 6spd.

 

I'm pretty sure that any year J32A2 uses the platinums except for the 6MT which uses Iridiums

 

according to NGK's website, the OE for 01-02 J32A2s were lazer platniums. you can replace it with lazer iridiums if you want since they give you the part number for those too. The OE for 03 J32A2s are lazer iridiums. there is no mention of auto or manual trannies but im sure it doesnt matter.

 

^ Yea but NGK didn't make the engine. Think about it, the J32A2 5AT is the same in 01-03, so it only makes sense that they all use the same plug - Platinums

Now in 03, the CL was available with a 6MT and that was the one with Iridiums. So maybe that's why NGK thinks that in 03, all CLs came with iridiums but it was only the 6MTs.

Trust me, I have an 03 CL-S and I switched out the original plugs and sure enough, they were Platinums

 

okay, since you changed them out, i cant argue with you on that. but im sure that the 01-03 J32A2s with auto trannies can use iridiums right? cause when im going to do my plugs, i wanna use the iridiums instead.
iridium > platnium.

 

Howabout we end this thread and just have everyone call their local Acura dealer and find out the part # for the OE Spark Plugs?

The Dbl. Platinum from Denso will be the best you can get for a N/A setup, Irridiums are mainly used for FI setups becuz they can run at a higher temperature range.

 

meh. the only planiums i would use are the lazer platniums from NGK. and in 03, the iridiums were used in the CL-S. I think AnthraciteBeast can agree with me on those two.

 

^ Whats the difference in Iridium vs Platinum? I know which ones are OEM but what are the benefits of Platinum over Iridium or the other way around?

 

i dunno. i just know iridium plugs came after platniums and they are more expensive usually.
