A few months back I replaced my spark plugs. I looked all over town for the NGK's everyone recomends and I couldn't find them. To make a long story short, I'm not positive but I think I may have installed the NGK's that go in a CL-P in my CL-S. I still get awesome fule milage on the highway (about 33-34mpg) and with typical city driving I get around 24ish mpg. I average anywhere from 300 to 400 miles per tankfull. I sometimes wonder if my power is suffering though. My question is, if I did indeed use the plugs for a CL-p in my CL-S am I gonna need a new engine soon or what will happen? Should I replace them with the correct ones ASAP? They have been in there for awhile now and I'm starting to worry. I love the car and don't wanna loose it over something so stupid.

Thanks for the help!

 

BTW- I still only use premium fuel to.

 

worse case scenerio is the plug you put in is getting hotter causing you car to pull timing

 

Will it return to normal if I put the proper plugs in?

 

your car will be fine, just change back when you have the chance.

 

Ok what plugs did you put in? part #

 

That's just it, i can't remember and i threw the boxes out. I'm almost positive they are for a CL-p though. I remember the part numbers being like 1 or 2 numbers or letters off.

 

33-34 mpg. wow. sounds good to me esp with gas prices the way they are

they are the same part number, this is right of of ngk's website. so don't worry if you did.

 

I KNOW for awile that the denso web site was showing the cl and cls using the same plug but when you went to the Tl it showed the colder plug for the type S

What milage did you change yor plugs? That some gangster gas milage

 

Wow... even when I take it easy I can just barely hit the 300 mark on one tank (all-city).

 

I changed 'em at about 46K

 

I wonder if it'd be benificial to use the plugs from the 6-speed on the 5-speed, considering that they're colder plugs?

 

If so, we should nominate Chris to be the first to try it.

 

LOL, what's the difference?

 

on a stock motor without FI don't try it, they will foul out and you will get a misfire, if they are too hot you will get pre-ignition aka spark knock. just leave the stock ones unless you plan on racing it or have FI.
