The Jeep comes with Platinum plugs from the factory.
And also a little secret-They are guarenteed from the manufacture for 1000,000 miles
Your Jeep should have Champion plugs in it.

"This is power loss miss answer" I have a 2006

why use, rumor to make that judgment.?

no engine runs for 300k miles, with out a tuneup.

this is true in 1900 and in 2014,

for the same reasons.

spark parts, fluids, belts , and brakes linings do not last forever

it called doing the service points list, stated in the operators guide.

in every car made.

those spark tips, , that is normal.. they wear away, after 30 to 50k miles.

the HV spark actually rips the atoms of metal off the tips.

and is aided by heat.

in fact, the first Atomic Bomb was made this why. (enrichment ways)

read new J. Robert Oppenheimer book (what a read that is!!!)

In electronics it\'s called HV metal migration.... or electrostatic, same.

yes, great call. but is SOP, standard operating procedures.

on some engines, it has COPS, if yes, then putting in new COP

boots, is a win. (too)

i bet the coil pack was ok

and only dirt cheap sparkplugs, and a HV wire set.

id bet. but no miles stated.

Spark plugs gap

no engine stated? wow. 3.5L? says no gap settings.
its in the FSM. many cars dont put it in the op guide as the plugs
are rated to 80k miles or more, and is not consider, operator deal.
and many folks think the new plugs are set in the factory , WRONG. (comment is for J plugs not surface fire tech)

i see you are there.!
many stores, list it wrongly too.... vast....
but you never said country car was sold.
in the USA we open the hood, look up and behold, its right there.
the vacuum and turn up sticker,
quotes to follow.........all.
the original equipment spark plugs installed in the Odyssey 3.5L V-6 engine are platinum tip spark plugs, and the plug gap must not be adjusted.
and other warnings, and the no file them warn.g
On CR-V and 4-cylinder Odyssey models, adjust the spark plug gap to 0.039-0.043 inches (1.0-1.1mm). On Odysseys with the V6 engine, check, but do not adjust the spark plug gap. The spark plug gap should be 0.039-0.043 inches (1.0-1.1mm). If the spark plug gap exceeds 0.051inches (1.3mm), replace the spark plug.

so 1mm , if not v6

What is most important maintenanace service at 30,000 miles for 2006 Jeep GC HEMI V8? is it spark plugs? Any suggestions?

the most important (in my opinion) is changing the transmission fluid( transmissions for those cost about $4,000.00 to replace) its supposed to be changed every 30,000 miles. ( spark plugs can last up to 100,000 miles before needing replaced.)

Do you need to replace spark plugs on a 2004 mitsibishi eclipse at 30,000 miles

its not ill advised. 30.000 miles is about where most spark plugs begin to lose thier potency. If it were me, i'd change them. they aren't expencive, unless you believe in all that platinum 4 bosch ****. get a good name brand set of spark plugs and they'll last another 30,000!

At how many miles do i change the sparkplugs and which are recomended

you should check your owners manual for manufacturer recomendations. If you do not have 1 then call or stop by you local dealership and talk to the service manager.

now personally I like the 50000 mile interval and prefer AC plugs.

Please advise me proper maintenance for 2007 jeep liberty sport 36000 mile. last service (34000) it was a list of supposed required stuff to do. just want to know what is needed and not. thanks

I don't know how much maintenace you have done in the past. Besides the normal inspections of the brakes, fluid levels and oil changes they do recomend changing the spark plugs and the axle fluid at 30,000 miles and adjusting your parking brake cable. hope this helps....

Spark Plug Life


30,000 miles is about right for changing standard spark plugs. You can install upgraded (and more expensive) Iridium tipped plugs which are claimed to last up to 100,000 miles but on a standard vehicle 30,000 is the correct replacement mileage interval.

Stick to the vehicles recommended service schedule and never mind what your friend says! Afterall these service intervals are already designed for a vehicle running on unleaded!

Carbon build up on plugs has a lot more to do with correct oil and oil filter changes than unleaded fuel.

Hope this helps. Please do rate my answer
