Anyone know the model/code number of what sprak plugs to use in an EF I6 duel fuel?
Parnell say to use spark plugs of a lower heat range, higher quality and qith a reduced gap by 10% of that used on petrol. Also, those iridium or plantnum or what ever they are called ones that are ment to last for ages, are they worth me looking at? |

In my old Duel Fuel EA I used standard NGK BRE527Y-11. I heard mixed stories about heat ranges, some say a colder plug, others standard plug.
I tried both and never noticed any differance. As for the Iiridium Plugs they are supposed to be the Ants pants, and last for ages, personnally I've never tried them, at something like $30ea I couldn't afford them.

I use the irridium plugs in all my cars. They're great. I get them for about $12 each. They last 120,000km. They're supposed to give you more power and better economy (I've never seen teh results on a dyno though) I've worked it our and if they give you 1% better economy, you end up saving money over the life of the plug. They also give a micro-discharge every time they fire than blasts the carbon deposits off the plug.
I'd trust Mr Ford with the heat range. He's done the research and knows what's best. Basically, you only need to chage the heat range if your plugs are fouling up or their electrodes are melting |

My car has Bosch W8LCR in them which is a little colder than the standard EL plug according to the bosch catalogue. Colder plugs cause the car to idle rougher on petrol tho....

Sorry EF plugs, I should read the post more clearly.
I only use NGK plugs NGK BPR5EY-11 gap 1.1 NGK Iridium BPR5EIX-11 gap 1.1

My cars got an aftermarket L.P.G. system, so I don't think Mr. Ford did the research for that. Will Iridium plugs work fine on L.P.G.? Anyone tried it? |

LPG cars run a cooler plug. just get one heat range cooler the factory petrol plug and you should be pretty spot on. out of interest i runn very cold plugs on my XR6 (straight petrol) the denso number is W20exu 11 the recommened is W16exu11 so mine are 2 heat ranges cooler and i've found my plugs are lasting longer and the car no longer pings under load at high RPM in 3rd gear. |

Just use NGK ZGR 6B-11 same as XR6 specs.good cheap plug ideally suited to LPG.Should be able to pick up 6 for under $20.good for 50,000ks.

I'm interested in trying the Iridium options. A.F.A.I.K. I'm currently using the NGK Tickford plugs - think that's the code that I was given on FM1.
Just been going through teh NGK website, for normal EF 4L I6 they say: Quote: Recommended Plug BPR5EY-11 1.1 Iridium Option BPR5EIX-11 1.1 For Tickford variant: Quote: Recommended Plug ZGR6B-11 1.1
Iridium Option BPR6EIX-11 1.1 So the Tickford ones are a colder plug over the normal ones then? |

Never heard of it untill recently. The plug temp relates to how much heat is dissapated through the plug. Obviously, the plug heats up when the engine's running because it's in direct contact with the air/fuel charge and the head. A cooler plug dissapates heat quicker so the plug runs cooler. Vice versa for a hotter plug. |

Read this link http://www.circletrack.com/techarticles/40118/ and that will tell you why you're getting less detonation. Given that a colder plug results in a slightly richer exhaust gas, your EGO sensor will be going nuts. |

For duel fuel, use XR6 plugs from any of the plug manufacturers

So no one has tried the Iridium plugs on L.P.G.? I think I'm gunna try the Tickford NGK Iridiums.
