SET OF 8 SPARK PLUG for LIQUID PETROLEUM GAS LPG Toyota Tacoma X-Runner 4.0L V6 with 1GRFE engine serial nr. (all model year) 333IP1LPEOR15LGS76P2PL1

ELECTRODE SHAPE VARIES ACCORDING TO ECONOMY- & DYNO-TESTS. PLS CHECK ENGINE CODE & YEAR OF PLATE SPECS. QUANTITY AS IN TITLE. LPG engines work on the same theory as gasoline engines. This fact allows anyone to easily convert a gas engine to an economic LPG hybrid. However, a few factors need attention. Different sparks for different fuels. It's not a secret but an axiom. LPG motors have higher voltage requirements. Since internal pressure and temp of combustion is higher in LPG engines, they need higher spark voltage for ionization than standard gas engines. Where a petrol engine might need 14.2 kV, the same engine converted to Liquid Petroleum Gas would need 16.2 kV. LPG causes fewer deposits and less fouling, so heat range choice could be one range colder than stock. However if you fitted a colder spark plug definitely how would your bi-fuel engine behave when running on regular petrol? Have you ever heard about misfires, flat spots, extreme plug fouling and soot deposit on projective electrodes? This is what you need to avoid. These high intension LPG plugs increase fuel efficiency, lower emissions and enhance engine performance. You can increase gas mileage, reduce harmful exhaust emissions and maximize horsepower. They are designed to outperform other brands in durability and productivity. Misfires have been significantly reduced consequently combustion conditions have improved dramatically, generating more performance. Multi-spark plugs increase HP. Auxiliary electrodes applied by a special patented technology on the insulator tip enable simultaneous flashover of 2 surfaces & one air-gap spark at one impulse of ignition system. Spark can flash along the whole perimeter of 360° auxiliary electrode. Spark gap protrudes deep into the combustion chamber & improves initial phase of spread of the flame front. Design ensures optimum mix ignition. If you are sick of wasting money on gas prices & looking for better performance, then these plugs are for you.
