anyone to recommend? heard denso and spitfire not bad.. i was thinking of changing.. but my car not sports car.. so just wan to change to something nice but not racing one

denso and NGk huh? i heard onli certain models can have certain type of spark plugs.. cannot anyhow change... izzit true?

check with the workshop 1st to be safe.Originally posted by choppers:denso and NGk huh? i heard onli certain models can have certain type of spark plugs.. cannot anyhow change... izzit true? -
How come no one ask about BOSCH Super 4 spark plugs? Four firing pin heads on the plug. I have one set ready for my next servcing. Heard anything bad about it? No news is good news.

Watz ur car model?
If u wan lastin n haf spare cash, can try Denso Iridium IR-16 / IR-20... But be prepared 2 spend more coz each plug costs ard $22. Tats y wanna noe wat car u drivin... If those continental cars den maybe more than e usual 4 pcs mah... Therefore more ex... -
those plugs u can get off the shelf at petrol kiosks? think quite cheap also. those things are ok lah, but dun last beli long. each servicing gotta change. iridium plugs on the other hand can last for min 2 servicing..... well, yi fen qian yi fen huo.Originally posted by Troy437:How come no one ask about BOSCH Super 4 spark plugs?

hey i dirivng an opel corsa........ that was y i heard form frens... that denso and spitfire is good.. btu i know there are so many different kinds within each brand... so how would i know which one is good? i know denso one can last at least 20k km before next change.. the rest i dunno... any enlightenment?

For normal cars it is better to use back the normal type of spark plugs prefer those stock type.... reasons being that it is cheaper..... as there is not much improvement to tok abt in the first pl.....
Denso Iridium is freaking expensive.... so not really worth it.... -
If u wan Denso, get Denso Iridium IR-20... Itz gd n lastin... Ya ard 20k km loh... Which is after 2 servicin sessions loh...Originally posted by choppers:hey i dirivng an opel corsa........ that was y i heard form frens... that denso and spitfire is good.. btu i know there are so many different kinds within each brand... so how would i know which one is good? i know denso one can last at least 20k km before next change.. the rest i dunno... any enlightenment? -
yah....this is one thing i would like to find out....
what kind of performance would u expect out of a good spark plug? what are u supposed to feel? -
1) Faster ignition the moment you turn your keys (Confirm).Originally posted by jiayong:yah....this is one thing i would like to find out....

2) Slam e-brake engine wil not die off (I tink so).
3) Faster pick up (I tink so too) -
The spark plug has two primary functions:
1.To ignite the air/fuel mixture
2.To remove heat from the combustion chamber
Spark plugs transmit electrical energy that turns fuel into working energy. A sufficient amount of voltage must be supplied by the ignition system to cause it to spark across the spark plug's gap. This is called "Electrical Performance."
The temperature of the spark plug's firing end must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. This is called "Thermal Performance", and is determined by the heat range selected.
It is important to remember that spark plugs do not create heat, they can only remove heat. The spark plug works as a heat exchanger by pulling unwanted thermal energy away from the combustion chamber, and transferring the heat to the engine's cooling system. The heat range is defined as a plug's ability to dissipate heat.
Not I write one.... found it somewhere..... -
Specially designed to meet the needs of serious enthusiasts, Iridium Spark Plugs offer outstanding acceleration, high fuel efficiency and long life. When you demand the most from your engine, rely on the proven performance of Iridium Spark Plugs.
Iridium is the personification of these qualities and takes premium performance spark plugs to a new level. A level that is expected from the world leader in spark plugs. -
spitfire series was quite hot during the 90s mhhh becos of the V series... if I am not wrg....Originally posted by choppers:anyone to recommend? heard denso and spitfire not bad.. i was thinking of changing.. but my car not sports car.. so just wan to change to something nice but not racing one It is another type of performance plugs that is built to improve performance.... at that time.... now the iridium technology seems to be more advance.... -
there is actually a part number or code number..... different cars will use dfferent ones..... so be careful when u buy them... the best is to get ur mechanics to buy for u.....
Spark plugs are classified according to size and heat range. Size refer to physical size - that is, the ability of spark plugs to physically fit a particular engine. For each size, there is a range of spark plugs that very according to their ability to get rid of heat. Those plugs that are slow to dissipate heat are called "hotter" spark plugs, while those which are quick to dissipate heat are called "colder" spark plugs.
If plugs cannot get rid of heat fast enough, they are begins to glow and cause pre-ignition, which is ignition of the fuel mixture before time. Severe pre-ignition can seriously damage an engine.
Conversely, if a spark plugs get rid of heat too fast, deposits will form on the tips, possibly causing plugs to short circuit. The engine will begins to misfire.
okie all this will help u understand more abt a spark plug -
hey thanx so much for the info..think will check with service centre then...... cheers

Yup, unless you are re-tuning your car. Upgrading the plugs might not be very useful. Saw a case recently, the intake valves were completely charred and damage due to pre-ignition. Pretty bad damage.... might be due to too high boost and low lifts from the exhaust cams...
