Thread: Spark Plugs for 3.5EFI on Dual Fuel?

Hi, LRHydrid 100,

I've a 3.9 V8i which I just converted to LPG they recommend
to use one-range colder and non resistor type NGK Vee-Groove
spark plugs and low resistant stainless steel plug leads

Your LPG installer should be able to advise you.

Because I had a service prior to fitting conversion, am still running
std plugs. however on 1500 Klm LPG check being done next week
and will get leads fitted then.
Will fit "V" groove at next service.

You'll love the diffrence in the back pocket LPG makes [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

Hope this assists,

Cheers!!!

Cheers Baggy,

When you do change them pls let me know the NGK model nuber you install and any results you find with them would be appreciated.

What sort of system did you install? - Impco type?

Talk again soon,

LRH.

LRH,

I've had a Sprintgas (Aust) unit fitted. by Mews Auto gas (Perth)
with lube kit [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

Because the Disco's doesen't accommodate a tank underneath, the most
popular conversion (here in the west) seems to be 3 x cylinder tanks
(look like scuba tanks) fitted inside vehicle with 63 usable litres.
Normal tank takes too much room and doesn't leave much usable space,
when there wasen't much to begin with anyway [img]style_emoticons/<#EMO_DIR#>/sad.gif[/img]

I've fitted board accross top covered in fabric (over tanks) with narrow
pull out drawer to store gear underneath, lost approx 210mm for
tanks, but gives flat floor in back, with disco's high roof line you don't
loose much in the end. I will post photo's when I figure out how to [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

Because tanks are small we fill up approx 2-3 times a week averaging
approx 180 kms for tank @ $16.00c (per tank) better than the $80.00c +
on petrol per week!!!!!!!!

Hope this helps you out [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

G'day Baggy,

The kit I am currentley installing is a Sprintgas system too - but with the 100L tank in the back of the seats. What is the lube kit?

Be interested to see how the performance and fuel economy goes with your LPG set up.

THX in advance,

LRH.

I tried the bosch 4 pronged plugs at about $8ea. Don't bother, the standard plugs were just as good on the Rangie [dual fuel] . I did notice an improvement with the bosch plugs in the 2.25 series III though.
