its not a bad idea to have the torque wrench. i use it on stuff like suspension parts and such, its good to make sure you get that stuff tight. put it also good for stuff like plugs so you dont make them too tight.
I called the dealer...they will sell you champion 439 plugs...they wanted 3.99 ea for them...i bought the same plugs at orilies auto and paid 1.99 ea. calls for .040 gap and 20 lbs of torque.
I just replaced my plugs with stock type Champions. After 57,000 miles the gap on the old ones was almost .060! I should get better mileage now. It wasn't a hard job, the rear pass. one is a pain but not that bad. Get the original plugs and do it!
There are no wires on the 4.7 and 3.7 but the Hemi does have wires.
The gap opened from .040 to .060 because of erosion of the electrode. I was almost double the recommended mileage to change them.
I have alot to learn. My Jeep is at 47 k and my dealer wants to do a tune up for the low low cost of 200 bucks. but it looks like all they are going to do is spark plugs from the right up they gave me. Also a windshield washer nozzle is broken and they want 135.00 to fix that. Does anyone know what else the 47k tune up includes and if its worth the 200 buck.
ohh yea they also want to clean my fuel system, what does that do ?
dude 200 bucks for a tune up and spark plugs isnt that bad from a dealership... i got a quote of about 400 bucks from my stealership to change out the plugs alone.
