Protect your Porsche from a possible IMS Bearing failure today! These kits should only be installed as preventative maintenance. If your engine has already suffered any type of internal damage, whether related to the IMS or to another component, we recommend the engine to be further inspected and diagnosed. Simply installing our DOF kit or any IMS kit on the market will not correct damage that is already present.
Professional installation highly recommended.
The patent-pending Intermediate Shaft Bearing Direct Oil Feed System (DOF) lubrication kit for all MY05-08 M97 Porsche engines to assist in preventing possible IMS failures by providing the necessary lubrication and cooling to the IMS bearing. Designed, developed & manufactured by TUNERS Motorsports. TUNERS Motorsports IMS Bearing Direct Oil Feed Kit (DOF) lubrication kit for 1997-2004 Porsche 986 / 996 models with the smaller single row or dual row extractable IMS bearing.
This is the ONLY IMS lubrication & cooling kit on the market WORLDWIDE!
The intermediate shaft bearing found on M96 and M97 Porsche engines require a constant flow of oil to provide the necessary lubrication and cooling the IMS bearing needs. Simply relying on “splash lubrication” or “mist lubrication” is not sufficient to drop operating temperature on the bearing and lubricate. The cooling benefit is a drop of 30 degrees F to the IMSB.
Included in the Direct Oil Feed kit:
- Patent-pending DOF Flange
- 3 micro-encapsulated Porsche bolts
- Spacer for single-row bearing
- Engine oil port adapter with crush ring
- 2x Cam Plugs
- 3,000psi hydraulic hose, DOT
- Fitting for hose
- Thread locker
The Direct Oil Feed (DOF) lubrication kit uses a patent pending custom made Intermediate Shaft Flange that utilizes a direct oil feed to the intermediate shaft bearing. It uses an adapted pressure fed oil line from a positive oil pressure feed on the cylinder head directly to an opening in the custom DOF Flange. This feeds fresh oil directly to the open end of the IMS bearing (after removing the seal to expose the ball bearings on the IMS bearing) providing a constant flow of cool, and filtered oil to the IMS bearing. By using a positive oil feed from the engine’s cylinder head valve cover, there will always be a consistent flow of oil directed to the open end of the intermediate shaft bearing. This is a cost effective way to help protect against IMS failure.
Special note when ordering: The DOF kit is specially made to work with the SKF bearings that we provide. We do not sell bearings separate from the DOF kit as they are made to work with the DOF patented flange. Bearings are now packed with their specific C-clip and spacer ring and no longer come in the DOF kit packaging. Please make sure to order the correct bearing for your application. Installing the wrong bearing or aftermarket bearing without the proper items will incur possible damage.
Tool Kit Rental Note: If you are renting an IMS tool kit, please note that you will have 15 days to return the complete kit from time of delivery to your shipping address. Once received back, a $300 refund will be applied.
