High Performance BRISK Silver Spark Plugs for TOYOTA Petrol, LPG & CNG Motor Vehicles
.




Fitting the Correct Spark Plugs for LPG - CNG or Petrol
Check to see what spark plugs you have fitted in your vehicle, if you have platinum or Iridium tipped spark plugs fitted they are No good for LPG or CNG there is No such thing as an iridium or platinum LPG spark plug! we recommend you replace your spark plugs with Genuine LPG / CNG spark plugs > Brisk Silver Spark Plugs are made for LPG - CNG & Petrol they have solid silver electrodes to produce a superior spark as you can clearly see in the chart below Silver has the highest Thermal & Electrical Conductivity where as Nickel, Platinum & Iridium are very poor, Silver spark plugs come in two types (YS) single electrodes for all vehicle types & The (LGS Premium) type multi electrode type theses can only be fitted to modern vehicles with electronic ignition systems they are not recommended for older vehicles with ignition points or poor ignition systems, the LGS spark plugs are specially designed by Brisk to produce incredible sparks across 2.9 mm gaps in a 360 degree firing pattern - theses are special spark plugs they cannot & do not require any adjustment they are ready to fit.

 Do Spark Plugs make a Difference?
Yes 100% - Vehicles fitted with Poor Quality spark plugs produce a weak spark, to ignite a fuel with a weaker spark the engine requires a much richer fuel mixture - with poor spark plugs you will use more fuel even petrol, when running a vehicle on LPG or CNG you need a much stronger spark due to LPG & CNG being a dry fuel it is harder to ignite than petrol so you need a much richer fuel mixture! most vehicles are fitted with lambda control systems like petrol injection vehicles which correct the mixture by monitoring the exhaust emissions this can lead to a serious problem running on LPG or CNG with weak spark plugs as un burnt LPG or CNG has an affect on the vehicles lambda exhaust probe sensors which makes the sensors read incorrectly (weaker) the vehicles Ecu or lambda control system detects this & tries to correct this by increasing the fuel mixture even more although the system now thinks the mixture is correct is Not it is incorrect the engine is actually running far to Rich not only is this decreasing your fuel economy but also increasing the exhaust emissions CO & HC no longer a green conversion in some tested we have found the emissions to be much higher than petrol emissions & failed MOT's, this also has an increased affect on the engine & exhaust temperature which can seriously damage the catalytic converter due to overheating.

 Common Symptoms found with Weak Spark Plugs
Poor Fuel Economy, Misfires, Poor idle, Stalling, Hesitation & Jerking under load, Less Power, Poor Performance in some cases undrivable on Lpg or Cng, Back fires, Engine management light coming on, Limp home mode, Exhaust system overheating, Lambda sensor damage, Catalytic converter damage, etc..

 Spark Plug Gaps for LPG & CNG
when fitting Brisk Single Silver Electrode (YS) spark plugs it is recommended to set the spark plug gaps to the manufactures recommended gap as for Petrol unless otherwise listed for your model like (DR15YS-9) -9 being the recommended gap = 0.9 mm etc… if the gap is not listed then use the manufactures recommended on some vehicles with spark monitoring try reducing the spark plug manufactures gap by  0.1 mm to compensate for the dryer fuel - The (LGS) type spark plugs are specially designed spark plugs which produce incredible sparks across large gaps like 2.9 mm theses cannot & do not require any adjustment they are ready to fit.

 Economy & Customer Feed Back on LPG , CNG & Petrol
Please Note: Fuel Economy on any fuel is very difficult to calculate as we all drive differently, all have different loads, all use different equipment & tuning of the systems, when fitting the New spark plugs the system should be retuned as most have be setup rich to work on the old type spark plugs, etc..  if you have tuning equipment you can do your own calculations by comparing the original tuning map to the new map tuning with the new plugs fitted, or by monitoring your fuel figures prior to fitting & then after, I always like to receive customer feedback of there test results, etc...!

Feed back from customer tests the results = on LPG increase in economy from 5 to 30% a few claiming more! - on Petrol up to 10% - Performance increase up to 5% - Noticeable while driving most customers say they have noticed the difference in driving the vehicle saying it is more crisp & responsive with better fuel economy, customers with prior problems like hesitation, jerking, very poor economy caused by poor spark plug ignition have found the plugs solved most problems & after retuning the system to use the correct mixture, etc...  Motor cyclist noticed the difference in power & power band smoothness as well as a slight increase in fuel economy, etc...

But note: this does not mean you will get an increase or solve any of you systems problems as many other factures must be taken into consideration & account like the increase in fuel economy can be used as power & performance depending on how you drive! plus any Vehicles faults with the petrol or LPG system/s & Poor tuning, etc...

The following Tests Mapping Charts are photos of the tuning done on a Toyota Amazon 4.7i V8 fitted with the Vogas gas injection system fitted with split fuel capability.

 The First Chart (left)
fitted with Original Iridium spark plugs the results = very poor economy on LPG, System had use split fuel to inject 30% petrol under load to stop misfires juddering due to poor ignition of the fuel

 The Second Chart (middle)
fitted with Standard Copper spark plugs the results = an improvement in economy & split fuel reduced to inject only 15% petrol under very hard load

 The Final Chart (right)
Fitted with Brisk DOR15LGS Premium Silver spark plugs the results = increase in fuel economy by other 30% compared to Iridium spark plugs, split fuel turn off running 100% LPG, no hesitation, no misfires or juddering, map greatly reduced

Tests showed the (YS) Spark Plugs produced nearly the same Fuel Economy Results as that of the LGS Premium Spark Plugs. But the (LGS) do out perform the (YS) in performance, etc...
