Spark plugs or not

[Liberty06]

I replaced all 6 plugs with platinum ones..Not too much $ but what Napa had and they seemed really great for about 2000 miles...Even had extra puch in the pedal it seemed...Now the engine feels like they have 20000 miles on them and the little extra is gone..Anyone have any plugs they really like that made a difference...I am ready to pull out the hair I used to have on my head..! Thanks

5224?? I don't have any reference to that part number for a KJ.

Edit: Just went and checked again, no 5224 recommended for KJ's on either Rock Auto or Advance Auto Parts. I did some google searching and found reference to the 5224 being used in newer Dodge Durangos and Dakotas.

Edit 2: Went to Autolite's website, it said the 5224 could be used for 05-07 KJ's, not sure why it doesn't come up for 02-04. The only difference between the 3923 and the 5224 is the tip style, is says the 5224 style is Special Power and the 3923 is just Power. I got a new set of 3923's going in my KJ as thats what everyone seems to recommend.

Autolite Plats only way to go.. pick them up @ Your local autozone.. I got all 6 of mine for like $2.99 a piece.. Link is here: http://www.autozone.com/autozone/ca...mWhere=&searchText=autolite&_requestid=329323

Knowing NAPA the way I know napa I bet you got NGK or AC DELCO.. and IMHO I hate NGK they can burn in the bottom pit of hell..

Chrysler made some changes to the 3.7 in 2005 which probably explains the spark plug switch from 3923 to 5224.

Never knew the later years used a different plug, learn something new every day!! I will tuck that away in the old brain.

There isn't Autolite over here, so I'm sticking to the NGK's in MOPAR envelope

Cheers!

[Liberty06]

Thanks all..experience was what I was looking for...Will give these Autolite Plats a try and put them in first sign of spring.

 

[AlexKJ]

Yeah Alex, but not every week, please...OP:use the search option, there are a gazillion threads about sparks...and oil.

OK OK you're right... it's just some days I'm less grumpy about the search thing ... But IMHO people don't searching it's the N°1 most common problem in any tech forum...

So next time, it would be only a JSTFF or UTFSO rofl2.gif

Cheers!
