A BMW M60 engine tune-up is a relatively simple procedure that even the beginner “Do it Yourself” mechanic can handle with ease.

Tuning up the M60 four liter V8 is really easy. Nope…we are not losing our minds here at the Repair Guide. Putting a new set of spark plugs and coil packs into this compact V8 truly is a simple repair. In fact we had forgotten how simple and straight forward a BMW M60 engine tune-up is, only to be pleasantly reminded while putting this article together.

The M60 4L V8 was BMW’s first eight cylinder engine in almost a quarter century. It was the power-plant in BMW’s premier lineup of luxury sedans and coupes during the ’90’s; the E32 530i/540i, E34 730i/740i, E31 840ci, and E38 730i/740i cars.

Putting a new set of spark plugs and coil packs into this compact V8 truly is a simple repair.

This eight cylinder work horse of the early to mid 1990’s was ultimately replaced in 1995 by the M62 4.4L V8. Notorious for reliability issues due to it’s Nikasil lined engine block, the M60 has been unfortunately black listed among many BMW enthusiasts. But many reliable cars still remain in service with M60 engines in them, and with proper care and maintenance they should be around for a long time.

The price of coil packs and plugs for the M60 engine is relatively cheap. Good OEM coil packs can be found for around $50-$70 a piece…plugs for about 5 bucks each. You should be able to do the whole tune-up for under $600, which is less than half than what you would expect to pay at the dealership. When purchasing coils, make sure they include the rubber connecting boot. The BMW Repair Guide always suggests using a good OEM brand for the coil packs…stay away from cheap “generic” or unknown branded parts (if in doubt, purchase our suggestion below). If the price is “too good to be true”, then you are probably buying an inferior part that could damage your engine.
