Čia plačiau apie 900 turbo žvakes. Tinka ir 9000.

Here's how spark plug heat ranges work:

The colder a plug is the more it will withstand hard driving but the easier it can be fouled, leading to misfiring. this happens when the plug cannot heat up enough to burn off carbon and combustion deposits. This plug does not heat up fast, it dissipates heat quickly into the head to maintain a colder temperature at the tip.

The hotter a plug is the easier and faster it is to burn off carbon and combustion deposits but the faster it becomes overheated when pushed hard (affected by hotter combustion temps). it dissipates heat slower and therefore has a higher temperature at the tip. overheating the spark plug tip will lead to incomplete combustion and pre-detonation.

So let's see about what to put in your car. Do you need a cold plug for hard driving, or a hotter plug that won't foul around town? Heat ranges are given in the numbers but they can be confusing in that they are not standardized.

Bosch heat range numbers start at 1 and get hotter the higher the number.
So 4 = pretty cold and 7 = pretty hot.

NGK heat range numbers start at 9 and get hotter the lower the number.
So 4 = pretty hot and 7 = pretty cold.

For *really* hard driving like a track day or heavy sustained hauling (speed not cargo) try using bcp8ev, or bcp8es. these plugs will be too cold to get good running while pussy-footing around town but damn they work well when you really push them. Like race-track push them. You can get as good, sometimes better, results using copper plugs in a turbo. The downside (and reason platinum is spec'd) is you will have to check and replace them more frequently. I actually run Bosch copper plugs in my rally car (the horror!) and the plugs used are w5dc (a 5 heat range in Bosch being roughly equivalent to an 8 in NGK). So if you're an experimental kind of guy you can give those a shot. The copper are much more reasonably priced so this offsets the need to replace more frequently. For what it's worth I've never had any luck with the Bosch platinums and the reason people stay away from Bosch plugs in Saabs is the poor performance of the platinums. They seem to work well in other cars though. Go figure.

So to recap:

NGK:
BCP6ES or BCP6EV for city/town driving (stop and go)
BCP7ES or BCP7EV for regular/hard driving
BCP8ES or BCP8EV for very hard driving/racing (this plug will foul with normal driving)
where the 's' denotes copper and the 'v' denotes platinum

Bosch:
W6DC (for regular/hard driving)
W5DC (for very hard driving/racing)
where '6' is a heat range equivalent to the ngk '7' range and where '5' is a heat range equivalent to the ngk '8' range, which is a colder plug than stock NGK spec (being a '6') or even the factory NGK 'hard driving' recommendation of a '7'.

Hopefully you've made it to this point with an understanding of *why* I'm saying you should use these plugs and enough knowledge to start doing your own spark plug thinking and not just regurgitating "buy my plugs because they will give you 5hp" marketing crap about a fancy new plug. If not, c'est la vie as the French say.

Nieko nesiskiria, 2.3 ir 2.3t eina tos pačios, gali deti. Kiek beje mokejai uz zvakes?

11 yra tarpelis tarp, nemoku ten termiškai paiskint, kur kibirksti skelia sitas terpelis yra 1.1 mm. kiek atsimenu taip.

dekui uz info. mokejau po 12 lt.s.miesteli serwiso parda priesais rimtomos serwisa.uzmirsau pavadinima to serwiso

[_Rolandas_]

As tik taip paklausiau, nes firmoj draugas padare po 7 lt., tokias pat.

as kur tais forume skaitinejau kad tokios zwakes per 18 lt kainuoja,tai ir buves nustebes

Taip jos panasiai ir kainuoja, tik kiekvieni vis kitur savo antkainius susideda, gal dar skiriasi kur gamintos, ant zvakes sono buna parasyta.

tiesa sakykit okaip stipriai tas zvakes reik prisukti,nes senosios keistai lengvai-tiesiog su ranka atsisuka?

Zvakes jau reiktu paverzt, ranka tikrai negali atsisukt, daug jegos nereikia,
bet truputi paverzk.
