lpg spark plugs

[Rowdey]

Ive fitted the plugs this morning and the hesitation/flat spot has completely gone. Havent tried running it on gas as yet but will report if its any better. The guy from ebay who i bought them off emailed me after (as i put a link to this forum) and gave the following information which may be useful.

Hi Matthew = Just a quick one on te forum you gave me interestung but a couple things with LPG & Plugs
1 you should never fit platinum or iridium plugs they are no good for LPG & can cause engine & cat damage - infact the only good thing about iridium plugs is they last longer but at a cost even on petrol on economy!
2: never reduce the manufacures gap more than 0.1mm for LPG it can damage the H/T coil/s due to increasing the current, etc... the 0.1mm less gap is just to correct the spark current for LPG which is a dry fuel & petrolis a damp fuel
3: Brisk Silver & multi spark plugs both work A1 in the Transite 2.3i LPG (how to choose! single point type for normal driving - multi point for performance) both give near equal economy!

Sorry guys, but i`m sticking with NGK. LPG-1`s that`s what you need.Expensive but tried and tested,Brisk just want to slag off everyone else but with no evidence or tech back up."buy them and try them" they said to me."if they`re crap,do I get my money back" I said........................................no answer.So NGK it is.

if not plugs check the valve clearances, these lpg connects even though they have hardened valve seats suffer with valve recession into the head

just as an addendum to this thread which i started, since i started using these brisk plugs, i have not changed one coil pack, van still running beautifully, best its ever run.....fuel economy, acceleration is better and its so quite.... well pleased....oh and no i am not a brisk agent. completely impartial.

Had stuttering this week from cold, and obviously only firing on three cylinders. Got better (back on 4 cylinders) during day for first couple days, but then getting more common at all times.

I bought the £30 premium Brisk plugs in Oct 2012, and have fitted Bosch coils March 2014.

For comparison, Mileage wise, i do less than 4000 miles a year.

Whipped them all out, and lo-behold..

Anyone else had problems..?

I have read this article a couple of times now and had to put my two bobs worth .
I have looked at the brisk plugs , they make a lot of clever but unsubstanciated claims ( which I am sure they are not allowed to !!) but have a very poor reputation on other forums ( especially the lpg forums ) as a company trading in the free market they are only 25 years old and I doubt if they know more than Champion or NGK or Bosch
I have always used the NGK Iridium plugs starting off with my smiley face mk5's and then on to my mk6 jumbo .
The plugs that worked great in my smiley were/are rubbish in my mk6 , misfiring, lack of torque etc I put it down to my LPG system . But on my last but one trip to Spain the misfiring was so bad that even though my plugs were nearly new I felt forced to stop and buy new plugs in the centre of France , I managed to get some from a L'Eclerc supermarket for 14.95 euros !!!
Having got the plugs , I was just about to fit them when I realised the air filter box lid was loose tightened it down with a luggage strap and all was well(ish) and carried on my deliveries .
Anyway time came to change my plugs and I thought I will try these cheap plugs and see what happens , fitted them and its like I have a new van !!!
The misfiring has gone, I can pull from 20 mph in 5th gear ( 3rd using the NGK Iridium plugs ) without hesitation . I will see how they go over next trip ( to North Africa ) and let you know if they are any good or not .

Off to France in a couple of weeks so am really interested to know the ID numbers for these plugs

[madmart132]

Hi Mealic I am fairly sure I bought them from a Le'Clerc Hypermarket ( wife has tidied the reciept !!) they are made by Marchal and the code number on package is M001
They fit Scorpio and Galaxy as well , nothing about transits on packaging but they fit and work well !! ( So far at least )

I fitted Brisk LPG plugs , I can honestly say I felt no difference .

Somewhere along the line I developed a misfire , upon inspection it turned out that the centre ceramic electrode had cracked and fallen off ,i will not be using them again , i put the Ford plugs back in ( glad i saved them under the seat ), and all is fine now .
