Title: correct plugs for a disco 1 with a 3.5 V8 EFI (lpg)
Post by: nickW on November 30, 2006, 15:22:48

recently my discovery has been missing slightly, so i thought i would change the plugs leads and coil to see if i could get a better spark

paddocks list some different models of spark plug but i was wondering which one would be best for my v8 efi lpg

N9YC

RN11YC

RN12YC

If its a 3.5 then use NGK BP6ES

I was using the recommended ones untill I found out about the NGK's, they certainly burn better.

Same as the 3.9 guys  

I've used NGK's in all my petrol cars for over 20 years. Can't beat 'em  :D

Seem to remember a thread recently where Range Rover Blues explained the R prefix on plug numbers... something about a resistor?

Might pay to check out the RRC forum.

Yea the bpr 6 es have a inline resistor in them to cut out the electrical noise but they dont work very well with lgp as the resistor cut the spark down. I now as mind had a set of these on when i got it and the lpg just keep missing but it run great on petrol. changed plugs and it runs great now on both

Just to confuse you all I now run BPR6EIS, because I can't get them unresisted so I look for unresisted leads instead.  Last set cost me £50 if anyone's interested.

Just bitten the bullet and bought a set of Magnacore leasds for my V8 (£92   :shock: ). The plugs they recomended are the non-resistor ones.

Range Rover Blues... if you need a supplier I can put you in touch with mine..

What for leads or plugs?  I have a set of Magnecore on Blue and good as they are for £92 I'd want them to fit :shock:  the last set didn't.

You might have missed it but BPR6EIS denotes Iridium plugs, they are not available unresisted.  The resister is radio supression so as long as the leadas are not 'supressed' too then it's not too big a problem, but non-resistive plugs are the ones to buy if you have the choice.

Yes... I know...

The diffirence in quality is significant and the information that comes in the box gives very clear guidance about how to use. Been led to believe the life expectancy is higher compared to others. and I got a free sticker.... :oops:

Decided to try them and see for myself as I trust the my local 4x4 garage who were pushing them.

Guess we'll see won't we!
