Product information "NGK spark plugs for Mercedes Benz M157 / M278 engines older caliber"
Special race spark plugs from NGK. They are suitable as an upgrade on uprated engines of the M157 and M278 series.
The factory installed spark plugs do not handle the high cylinder pressure of the M157 very well due to the very small tip of the electrode, which often causes misfiring problems even on standard vehicles.
