Stupid Question

A freind of mine brought his 300 Hemi in for service to his Dodge dealer
and thay said he needed a tuneup. This service person said he had 12
spark plugs. Yes 12????? Now I don't know anything about his engine but
I found that strange. I know V8's are 8 cylinder so is this stupid or
what?????? Are thay just trying to rip him off like most Stealer's do?
Thanks, Charlie

 

I changed the plugs in my 300m after 8 years (75k miles). You shouldn't
need to change plugs on a relatively new car at this point.

That's wrong.

Chrysler never made a 12 cylinder engine (at least not in a production
car).

Most was the 10 cylinder engine (take a small block 360 and add 2 more
cylinders). That engine was put into the Viper and some Dodge Ram's I
think - and nothing else. I don't think that even the SRT's had 10
cylinder engines.

 

They must be lazy at that dealer. Gen 3 hemis are dual plug so it
should have 16.

 

Now that you mentioned it I think his is a 2007 300 SRT. This car has
great lines and all black with very little chrome makes it more
impressive.

 

The Hemi has 16 plugs. AFAIK, Chrysler has never made a twin-plug
six. So your friend either needs a new mechanic or needs to clean the
wax out of his ears ('cause he misheard, or didn't get some details
about a bad ignition system frying 3/4 of the plugs, or something).

 

Sounds like an over-zealous service writer that didn't see the rear dual
exhaust pipes. OR he could only see the front three cylinders on each
side, but knew it was a dual-plug setup. Hence, 12 spark plugs.

If they are using platinum spark plugs, no real need to change them
until about 100K or so.

Sounds like a flakey deal!
