Re: Hemi spark plug change interval?

Spark plug change on the 5.7 is pretty easy; I've already done mine and will replace my wife's this weekend. if you have no experience changing plugs this isn't the vehicle I would want to learn on but if you are experienced it's an easy job.

I would jump all over $250. My local dealer quoted $360 when I asked. I only have 48k on the truck so I have time.

Re: Hemi spark plug change interval?

It's a pretty easy job. I did mine yesterday in about 2 hours. I highly recommend a 3/8" breaker bar and a 3/8" universal socket.

Re: Hemi spark plug change interval?

When the spark plug replacement is added to the fuel mileage difference, the cost factor swings from Hemi to CRD. Actually, now I really want to compare the "feel" of driving the Hemi to driving the CRD before deciding.

You should have already done it. The change interval is 30k miles.

Oh the previous owner did it at 30k ( I have all the service records) so I have a little while longer until I need to do it again. Just planning for the future I suppose.

Considering taking my Hemi to the dealer for this work, if its $100-150 for the job I have no problem. If its $300-400 I'm doing it myself. Anyone know what dealers generally get to perform the plug change?

It's about $35 worth of plugs, shipped from Rock Auto. I just ordered mine. You also get an $8 rebate on them.

Beats the heck out of the $15 Iridium plugs my old ride wanted, even though there were only 6.

I don't get why people talk about the plugs like it's some big expense. You do it less often than refill the piss tank on the diesel, and it's cheaper.

Where did you find them on Rockauto? I put in the model number and got zero results.

Re: Hemi spark plug change interval?

around $64 for the OEM plugs ordered online, about an hour or so of your time and change the plugs every 30-32k miles on the Hemi.
Oh, and you need 16 of them! Put the OEM copper plugs in - no reason to spend the $$$ for anything else when you have to change them every 32k miles. And no real improvement in performance gain with platinum plugs etc.

It's a Champion 446. If you go through and look at your car manually, you'll find them under the Ignition part. Works for 2011 Grand Cherokeee V8 at least. $1.73 each, before rebate.

From my research, the Champion pugs are the OEMs, they're re-branded and apparently nearly tripled in price for resale by Mopar. Have been on Hemis for many years now.
