well i was looking at sparkplugs.com thinking maybe they were cheaper then the old parts store, but i was looking at ngk iridiums...not sure which one of the iridiums but heard the iridiums period were a good burning plug and along with that purchase i am going to get 8.2 shorty wires

I remember reading somewhere not to use iridiums in the Hemi ( although some members use them to no ill effect ) but the regular plugs work just fine ( I used the NGK 4306 in mine ). I finally changed the plugs in mine @ 56,000... I know, way overdue but the truck was running fine and no loss in MPG... changed them and did not notice any difference... old plugs looked fine with the exception of a really wide tip.. really glad I changed them when I did as a few of them were really tight...

Im scared to even think about changing my plugs. I already have them, Im just waiting for one of my friends to help me with it. Im too scared Ill f something up.

Maybe someone can calm my nerves? Cause as soon as I get the new plugs in (NGK 4306), Ill be running a 100 shot! OH YEA!

I bought my plugs at advanced discount auto for $2 a pop. Came to be $32 even. Love have friends who are managers.

The NGK's are fine. Several v-groove and u-groove plugs out there, all fine with the hemi, no exotic metals needed.
Just plan on devoting an hour or two to doing the work. Plan on laying on your belly on top of the motor to gain access to some. Make sure you have a variety of ratchet extensions and at least one universal swivel for it as well. Make darn sure you have a really good spark plug socket, one that has the rubber insert that grabs the plug firmly.
Make sure you gap the new ones before you even start swapping them out.

It's all just unbolt and bolt, unscrew then tighten. Real simple stuff. Take your time and enjoy the satisfaction that comes with knowing you did it yourself (and saved a bunch of money by not taking it to the dealer).

Yes I agree totally! IMO I would start with the passenger side to get the hang of it. The coils are held on by two 10mm bolts (4 coils per side). Also, get a can of anti-seize and smear that on the new plug threads. Do not skip this step (aluminium heads)! Onto the driver's side the two worst plugs sit just under the brake booster. The way to get these plugs out is to drop the spark plug socket into the hole followed by the extension. Hope this helps :gr_patrio Kevin

No, more like less than $50. Again, you don't need iridiums or any of that jazz. The NGK's mentioned in other posts are good quality.
The stock Champion plugs that come in the hemi from the factory are just regular spark plugs, no fancy metals. Mine looked fine when I first changed my plugs at 50k miles.

I only have 15,527 miles on my truck as of right now.

The only reason Im switching is cause of my NOS system that Im installing. But it seems a big hassle for something so small.

I changed mine on my hemi. Took me 4 hours. I'd also recommend getting a tube of dielectric grease. Put a light coat of this grease on the inside of the spark plug boot. Makes it easier to install and remove.

I changed my plugs @ 46,000 miles. It was a pain but very straight forward. Another tip is to remove the Air filter box and HEMI hat from top of motor, this gives you good access to the passenger side plugs. I would agree that you really don't need the high dollar Iridium or platinum plugs but everyone has their preferrences. I used the regular NGK V groove plugs and they seem to work just fine. I did notice the stock plugs were all gapped higher than recommened gap (.45 I think). I did notice better acceleration and slight improvement in gas milage.

^^^ What HE said. This will save you tons of headache on the 2nd or third plug swap you do (provided you keep the truck that long)
