Water Pump Stud Kit fits M20 - E30 | M20WPSK

Replacing a water pump on an M20 engine can be a real PITA especially when it's time to line up the bolt holes to the block. Our solution is to upgrade the OEM bolts to stainless steel studs and never worry again. Our stud kit, once installed, allows you to easily align the paper gasket & water pump. A secondary benefit of our stud kit is the additional strength for the water pump since it is exposed to lateral load from the timing belt tensioner. This is a must have upgrade for all M20 owners. We suggest you use Loctite when installing.

Kit includes:

• 3 Stainless steel studs

• 3 Lock nuts

• 3 Washers
