This is just my 2 cents worth Ive tired about every spark plug out their for my 2006 jeep liberty 3.7L Limted. My mileage really sucked & I have a very heavy foot as well. Had a friend tell me about 2 months ago that the 2006 libertys came out with Autolite 5224 spark plugs installed at the factory. I said no way they came out with Champion spark plugs installed. To make a very long story short I decided
The 2.4 gasser uses one coil pack and 4 spark plug wires.Just follow the plug wires to the spark plugs. Dont forget to change the plug wires also when changing the plugs.If there is any oil in the spark plug tubes(oil will be on the wire boots) you need to chnage the valve cover gasket and tube sealscommon misfire cause in those types of engines.

I know I didnt just hear someone say bosch and spark plugs in the same sentence on a jeep site. Yeah Jbarthol called it some of us would be on here to say do not use bosch anything that screws into the engine. Even euro trash is going to other brands. NGK coppers are the exact OE plug and most KJs have the part number on the emissions sticker even. Some dont like NGKs and use Champions. The 4.7L(sister

My local jeep dealers Service Dept. said 0.044 in. is the correct gap for the plugs.

I have a 2006 liberty Limited. I used Bosch Platinum 4308 for 55K miles without any issue averaging 17 to 20 MPG combined cityhighway. I reside in Missouri and have to use ethanol blended gas which reduces mileage. After reading this forum I went with Autolite XP5224 Iridium&8217s. The jeep runs great. I have pulled my 3500 boat on this first tank of gas so no clue as to the mileage. I just want the
Note The 2003 is a KJ liberty. Doing the plugs cold yourself is fairly easy. Most use Autolites but I chose to use the stock NGK as listed on the under the hood sticker the gap is also listed there. Tool wise I used a 12 extension had 6 and 3 also available with swivel compressed air can anti-seize and die-electric grease. I did remove the air inlet hose to the throttle body from air filter as well as hang the coolant expansion tank on firewall up out of the way of passenger side rear spark plug. On the anti-seize I used just a very light sniff of it on a few threads to make it easier for removal next time. I did not over tighten them just until you felt the plug seat. (just a bit less than 14 turn) I would normally check the gap of each plug before install as well. I replace them every 25k miles. Here is a video that kinda funny but it shows the removal process you can just put the die-electric grease on the out side bottom of the coil pack.

I have to call BS on the miss fires and an issues I have a 2005 liberty 3.7L and I have nearly 70k on the plugs and they are the Platinum plugs (plus 4) and I had NO ISSUES outside of the Dealership telling me those are not made for the engine. My answer back is - Why are you telling me this for so you can have me in for tuneups more often Sorry I change my own plugs and a stick with what works and at 170k on the jeep and runs just fine with no issues. Mark

The plugs are equipped with tapered seats.
The jeep liberty Maintenance Schedule contained within the FSM as well as the Owners Manual clearly state the spark plugs are to be changed at 30K miles. The manual i have says only NGK plugs of a specified number as well. The reason they want you to use NGK is for the copper core. Some confuse that to mean it is also a copper electrode but it is the core of all NGK plugs that is copper. I believe

I could have sworn Ive heard people on this forum saying they used them anyone have a part number I used NGK platinum on my 07 and they work great. I have used them before on another vehicle and they lasted forever.
I have changed spark plugs about a dozen times in my liberty and I have used anti sieze lube every time. I have been buying my plugs from my jeep dealer for 2.00 each. Never had any trouble.
ive pulled plugs out of some of those 100k mile vehicles at 60K and they looked more like ceramic glow plugs at that point spark plugs are a prime example of declining return on investment you put in a new plug and every time it fires heats up cools down it degrades they dont magically peter out at 30k 60k 100k.. or whatever they slowly degrade. So slowly that most drivers never notice it until they
This guy gives a good explanation on how to change them httpm.youtube.comindexdesktop_u...vDxsEOCqhHx8 He shows where the hidden spark plugs are I hate how jeep doesnt want you to know about the plug behind the steering wheel
and those irdium plugs dont have the correct resistance and you see the result. If youre right and they are in fact the wrong plugs which plugs should I be running And wouldnt all six plugs be the same in that case The last plugs were replaced by mechanic so I had no idea which ones went in. This time I called the auto parts store my machine shop has an account with and asked for plugs for a 02 liberty
The cost difference when I ran the numbers was surprising... after 14K I thought Id check the plugs as I was feeling and hearing a slight miss... they were worn rounded had nearly an extra .020 gap due to wear. After using platinum for 20 year s on my other vehicles and getting an easy 90K on them without any visible signs of wear I tried to buy platinum for my V6 liberty (2002) - Bosch at that time
I called NGK and they recommend that the jeep liberty (v-6) stick with the (OEM) plug (V-power). The OEM plug has a coppor center electrode (ALL NGK plugs do) but it also has a copper ground electrode. The plat and the iridium one does not. Note Direct quote They are options and they should work ok but for best performance stick with the v-power (OEM) plug.
Hi liberty V6... I dont think the Bosch Platinum 4 plugs are a good choice for jeeps. Platinum just lasts way longer than a conventional plug but robs you off horsepower mielage etc. They typically last 100000 miles but are a lot more money.. In the end its the same as buying copper plugs for a lot cheaper and changing them every 30 or so... The best conductor of electricity is SILVER.. It is not platinum...
spark plug scocket with 2 extension universal in the middle and a 6 extension to the rachet will save you having to diconnect anything to get to the back plug. The NKGs work well in the liberty.

The KJ uses Champion 344 RC9YC plugs. They are 1.50 each at any auto parts store and you can get them looked up under either of the part numbers Ive listed. The GAP for these plugs and your KJ is .035 i thought the oem plugs for liberty is NGK maybe im wrong...

the hotter spark the copper plugs give but you are wrong on everything else.Your ignition system is set up with the resistance of copper core plugs built inchange that resistance(platinum plugs) and you throw the PCM in a loop and it tries to compensate which always ends up in either misfiresburnt coilsbad mpgsgenerally running very rough and extremely shortened plug life (seen platinums in jeeps
