Olen tähele pannud, et paljud kasutavad plaatinast küünlaid, kuid sattusin sellise teksti peale.



Spark Plugs

There is no reason to deviate from the factory-recommended Bosch or NGK spark plug specification, changed at 30,000-to-60,000-mile intervals, depending upon the car and severity of service. Basically, any BMW produced after 1993 can easily run 60,000 miles on a set of spark plugs.

The factory also has part numbers and applications for “100,000-mile spark plugs.” These are good too, and are capable of 100,000 miles of service assuming no other problems, which might cause them to foul during that time. However, in engines with spark plugs recessed into the middle of the cylinder head, oil can leak into the spark plug recesses past the valve cover gaskets. This is a hidden leak if the plugs are left in service for an extended period of time, because no one looks in there until they’re changing the plugs or chasing a problem. An oil leak in the spark plug recesses, left to fester, can cause ignition coil failure and even ECU failure. So, even if you want to leave the plugs in service, you should at least check the spark plug recesses for signs of oil leakage at least every 60,000 miles. And at the point you’re in there, you might as well replace the plugs. This is the issue with 100,000-mile plugs.

Moreover, while you may not have any problems running spark plugs for 100,000 miles in some BMWs, this does not mean the plugs will not be worn, or that that wear is not affecting engine performance. In other words, for optimum engine performance, most BMWs want spark plugs every 30,000-to-60,000 miles. M cars except the US specification S50/S52 powered E36 variants want plugs about every 15,000 miles.

Stay away from platinum plugs in BMWs. These don’t last as long as the regular Bosch copper or silver plugs and NGK plus, and have been known to fail in other ways. The regular old Bosch Platinum single electrode plug is, however, a very good choice for cars OTHER THAN BMWs.



Mida nagu arvate sellest? Või kui minna siiski plaatina peale, kas peamine valik oleks http://www.ebay.com/itm/BMW-NGK-Spark-P ... 347wt_1064" onclick="window.open(this.href);return false; ?

Tundub nagu rohkem mingi reklaamjutt, milles terake tõtt sees
Kui küünalde vahetusega samal ajal võtta ette klapikaane tihendi vahetus, siis vaevalt seegi alla 100000 km jäigaks muutub ja lekkima hakkab (kui on ikka vähegi korralikuma firma toodang)
Aga milleks ajada asja keeruliseks, tehas näeb ette NGK BKR6EQUP plantiinumid.
Parim koht nende ostmiseks eBays: http://www.ebay.co.uk/itm/NGK-spark-plu ... 3f00d49fee
Ca 45€ eest saab terve komplekti koos saatmisega

Ma vist jään ka selle juurde, et pole mõtet asja keeruliseks ajada.
