Hey all, I am past due a spark plug change and was curious...which do you have in your rig? I imagine there are many different options depending on how you drive your Libby. I personally use mine as a daily drive and weekend trails. I am debating the AC Delco Platinum. I thought about the Borsch Plat but have heard some horror stories.

I use Autolite double platinums,Bosch platinums are good also(don't get the +2 or +4 junk).All those +2,+4,and E3 plugs are not worth the money and can cause major problems.

Denso Iriduims are about the best plugs you will find,though about $12 each.

Sounds good. In general do you swap out the wires too when you change the plugs or does it really depend on if they are damaged?

No wires unless you have the gas 4 banger,on the 3.7 V-6 has a coil right on top of each plug,6 plugs and 6 coils,

Yeah mine is a 3.7 V6. Do you switch out the coils each time?

I have the Bosch +4s. What kind of problems can they cause?

No need unless you get a OBDII code,though they are only about $45 each,might be worth the extra cost after 100,000-120,000 miles.

The +2 and +4 Bosch plugs are known for one of the 2/4 grounding tangs to come off the plug and not play nice with your piston and cylinder walls(rebuild time).Just like NGK plugs have a pretty common problem with the electrode coming apart and doing cylinder damage in modified engines.

I have never gotten any codes but then again no idea how to get a code :D Mine is a 2002 Limited 4x4 with just under 84k miles. Over the last week or two I have been checking out all the things that I might have to or should change out. IE: Shocks, plugs. Hell, I am even seriously debating tossing in a remore oil filter as I really think the designer just wanted to screw with us on placement. IMO

What, you don't like scraping all the skin off your knuckles when you change your oil? :lol: I found that a bit tricky the first time I did it, especially since the mechanics at the dealership torqued that filter on REAL good. It's just not easy to get it started when it's turned down that tight....Now, though, it's not hard for me to get in there and change it. I just tighten the filter snug and a bit. :)

I like where it is. the mud packed in the skid plate soaks up the oil that comes out when you pull the filter;)

anybody had this problem with a KJ or is this a just in general problem? ( I just put the Bosch IR Fusions (4 points) in 2 weeks ago :cry:

I installed Bosch Platinum +4's in Decenber, only because I had purchased them from Amsoil last year when I purchased my KJ and was converting everything to synthetic. My mechanic would only install Champion regular plugs, After installation I have seen no improvement in milage or performance.
I lost all faith in Autolite plugs when years ago I tried them in my 260Z and the pouled out in 5 days. I'm going to go with NGK Iridium IX Spark Plugs 6441
I can get them for $7.35 each from Amsoil, otherwise I would go with Denso. I've used Bosch, NGK , of Denso for the last 15 years. Except for these +4's I've never been disapointed with any of these plugs, I saw no change what so ever from the +4's to the plain old standard Champion plugs. In fact the biggest improvement I've experienced is installing the PVC pipe going from in front of the radiator into the bottom of the air box before the Air filter. I've experienced an improvement in milage and an extra seat of the pants kick in performance. This isn't just a feeling my ScanGuage Series I reflects improvements all through the various readings. :twisted: :twisted:

Pics and Links please. I've been running +4 plugs in my Astros for 6 years, 25K miles a year with no problems.

I have the Denso Iridium plugs. Nice plugs, no real noticeable difference from the plugs that were in there...at least I won't have to worry about changing them out again until 180k! (at that time I hope to add 2 more plugs)

When I did my plugs last I used Autolite Double platinums... (per Troy's recommendation).

Relatively Cheap (~$35 for 6) and seem to work great...

Indeed, I believe these will be my newest plugs. Thank you for your help. Should be a nice easy swap out. Last thing I had to do was swap my radiator, apparently I hit a bump in Colorado near Westcliffe and my jeep did not like it, flexed just enough to put a small crack in the plastic.

Post subject:  NOLOGY Silver electrode !
Have you ever try this ones ??? there are nology brand, and the problem here is... those don´t have any resistance (ohm´s) and maybe without a resistance can occur ECU failure or any other issue with knock sensor, coils, etc... ??
