Question Shorty Spark Plugs

Hi all,

I had a question...

I am getting ready to change the plugs and wires on my '02 PT and I noticed something odd when I compared the plugs.

The current plugs are Bosch Super Plus Copper FR8DC+ (7927) and they seem to be 1/2 inch shorter than the ones I am going to use - Champion Double Platinum 7570.
Everywhere I look, the correct plugs are the Champion 7570 (plat) or RE14MCC5 (copper).

Did the "Stealer" put in the wrong plugs when I asked for performance plugs and wires 6 years and 30,000 miles ago?

Thanks

Classic,

the stock, Champion RE14MCC5 plugs I took out of my 2003 non-turbo PT are the longer plugs. I can only assume you've been running the wrong plug, although you didn't mention any problems with the shorty.

Maybe you'll get better gas mileage now? I'd definitely go with the longer-version.

I hope you can get the correct plugs to thread in ok. The short plugs allow that 1/2 inch exposed area to carbon up making it difficult to thread in the new plugs, be carefull!

Answers from the Internet:

If the plug is to short, the spark will Not ignite the fuel correctly and give poor mileage, performance and may cause check engine lights. the same can be said if the plugs are too hot or cold.

Thanks for the replies. The only things I have noticed since the shorter plugs were put in were a decrease in average gas mileage between 1-2 mpg and a slight hesitation/stumbling at highway speeds (60+mph), but I never thought anything about it. It has only been a few weeks that I notices loss of power (car lazy on take-off) and a rougher idle. When I pulled two plugs out one was gapped at .42 and the other was gapped at .48; I guess the ground either travelled or the "stealer" did not gap anthing.

I hope I do not have much carbon built up-in the head, but I guess I will find out when my wires come in.

There goes another point to the "Stealer" who has conveniently gone out of business a couple of years ago.

Thanks again.

Now we know a good reason why the dealer went out of business ....

Crewzin, I was waiting for a tiny rabbit to pop out of one of those spark plugs, but apparently that guy, wearing the rubber gloves, with the tiny wand in his hand, was not trying to conjure anything, after all.

The 2.4 / 2.0 DOHC used the same plugs for years until the "PT" head.
It seems a common mistake.

You are correct though, the dealership should know better, but just
doesn't care! If they screw up, theyll just blame it on you anyways.

UptownSport:...
That is what I was thinking. All my research into the Bosch plugs FR8DC+ (7927) showed they were for the 1997-2001 Neon. (There is hardly anything out there for those plugs.)

Thanks for confirming.

Another one, from just what I've found must be very common
