Its the only sparkplug i have managed to find here in philippines that fits my engine, just wat to know if is suited for my car before i have to look abroad
I cant find anyone that has a Bosch sparkplug recommendation guid or manual that has subaru listed on it in the philippines. or maybe their's no demand for this particular car where im situated for your product, maybe?
i'm wanting to know if the BOSCH SUPER 4, FR78X sparkplug is suitable for a 98' subaru WRX STi Ra version 4 or 3, engine # EJ20-796240,
And also what are the advantages of this sparkplug type over the platnuim and or irridium plated sparkplugs?, Salesman wasnt much help but its the only sparkplug type that i've found that will fit my car,
Your recommendations and feed back for this issue i have will be much appreciated

When your engine misfires fuel is still being pumped into the engine, it's just not being ignited. You need to find the cause of the misfire first. It could be: a bad sparkplug, a bad sparkplug wire, a leaking head gasket, a bad ignition coil, or cracked engine block. I'd start with the spark plugs first, then the ignition coils as they commonly fail. Good luck!
this issue sounds like u have a bad ignition control module,located directly under ur coilpak. thats wat they do wen they get hot aftr driving a while, shut off while driving(u must b loosing spark to ur plugs)an restarting wen cooled off. one way to check this for urself would b to purchase a spark checker at autozone or pepboys fairly inexpensive, an wen ur car dies, open the hood remove one sparkplug wire install tester between plug an wire, or wire an a good ground an have someone crank engine while u look at the tester bulb,if it lights up an pulses uspark is good,if it doesnt lite up at all while cranking engine ur spark is gone an thats ur problem possibly crank a sensor or the ignition module we mentioned earlier. try mounting the spark checker before the engine dies so u know wat a good spark will look like on that checker..... hope this helps good luck
With you hood open and you are standing in front of the car sparkplug wires need to be removed,i suggest you remove them one at a time, under each wire the sparkplug is threaded into the cylinder head,using a 5/8 sparkplug socket remove the sparkplug and replace it with new properly gapped sparkplug.Note:if you remove all sparkplug wires at once the factory wires are generally numbered 1 2 3 4 the sparkplug closesed to the passenger fender is #1 and the one clossesed to the driver's fender is #4.Standing in front of vehicle the PCV Valve is located between #3 and #4 on the backside(intake side) of the engine fitted down into a rubber hose
first things first, turbo charging a car that was not turbo'd from the factory is a bad idea unless your going to put in forged internals and fuel managment system and then tune it, turboing a NA motor will soon lead to distruction even if its brand new. if you want more info i can give you my number i build allwheel drive turbo eclipses and have alot of knowledge in that area. if your set on turboing your car dont put in another engine use that money to forge internal your bad engine, then buy a turbo kit because you have no clue the pains of building a junkyard turbo, you can get a pre programed ecu to swap that is mapped to that specific turbo and engine. just let me know if you want my email and i will help you in either path.
If you put larger injectors in the engine without the proper fuel
management then all you are going to do is run rich and get horrible
gas mileage. The only way you will need larger injectors is if you have
forced induction or a full motor high compression build.
