Title: Spark Plugs - What's best
Post by: jay140285 on May 20, 2011, 09:22:39 AM
4.7V8 WJ

Jeep is going to be serviced next week, Its having the following:

All Filters Changed
Engine Flush and Refill
Oil Change
Gear Box Oil change
Spark Plugs
Oil Sender oil seal replaced as its leaking.

What spark plugs are recommended (its now on LPG) - just read on the net that Champion Copper plus RC12MCC4 are one set to use? they are £2.77 each / also got NGK ZFR6F-11G £3.47

or these??

Denso Standard Recommendation
KJ16CR-L11
£2.72


Denso Iridium Power
IK16
£6.76
 
 
Denso Iridium Tough Plug
VK16
£10.18
 

I know there is an additive for the Diffs (they were done before I brought it), is there an additive for the gear box that is needed, and finally what oil is recommended.

Many thanks.

James

You may need to change the heat range of the plug if you have lpg so speak to a propper installer to see what they recommend, got to admit tho I have always had standard plugs in lpg jeeps I have had with no problem.

How come jeep dealers seem so good on price compared to other main dealers?

Ask your LPG installer about plugs.  My XJ used to eat the standard ones.  I switched to NGKs (I think.....it's been a while) but your installer will be able to advise on which to go for.
