The Ultimate Stainless Steel Oil Filter

One Middlebridge owner has had great results using one of these top quality Stainless Steel Oil Filters, (See web link below, highlighted area for specification and images at base of page).

Hi Peter,
I have now confirmed we need to go for the S15 type filter, this is the 3/16th thread and a 3.5" housing I will need to order one in from K&P but wont take very long to get here, let me know if you still wish to order,

Many thanks

The engine originates from 1989. It is the same as fitted to the Ford Scorpio, 2.9 EFI (Cologne) with fuel injection.


Just checking with K&P to check fitment as they in America have the same engine fitted to a few trucks, Bronco etc, If you can fit a 3.5" in there then use that, as the more filtration the better, and also the casing is that little bit bigger also, Will be in touch when i get a confirmation on fitment

Thanks Jason


I will include a couple of seals, here are the usual sizes available a C2 size may be more suitable, as its 3" long still giving a major oil flow increase to the standard filters.


Good Morning Peter,

Thanks for the email,

We can sure do a filter for you, if you can measure the depth of the filter you have or the clearance you have we can sort out the correct filter for you, sizes range from 2.7" to over 3.5" in depth, the sierra Cosworth uses the smaller one my guess is yours may be simular, i will try to find out this end the size needed but if you can check also that would be great.

We recommend the K&P Micronic Stainless Steel Oil Filter be cleaned frequently when first purchased or when engine work has been performed. This will give you a feel for how much debris is being filtered out of your machines oil and help you decide how often you want to clean the filter for your application. At minimum, clean the filter with every oil change.

Remember, oil is the lifeblood of your machine, keep it clean!

Before cleaning, inspect the element and housing (spin on models) for debris. Since in nearly every case the oil flows from the outside of the filter to the inside, the debris will be caught on the outside of the filter element and on the magnet set into the top of the spin on models.

Closer inspection of the debris can be achieved by flushing the particles into a clean light colored container. Monitor the debris from oil change to oil change. If something is significantly different in the amount or type of debris from the last cleaning or two, wemrecommend you investigate further.

Wash the reusable stainless steel filter element in clean solvent, gasoline, kerosene, aerosol carburettor cleaner or any other degreasing agent. You can even finish the cleaning process with some common dish soap and hot water. For stubborn debris, you can use a soft bristle brush to help dislodge particles from the screen. If you have compressed air available, blow air through the filter starting from the inside out, to remove any small particles or cleaning agent from the screen. If you don't have compressed air, let the element air dry or use aerosol carburettor cleaner or something similar to displace the water. Finally, if you have a spin on model, clean the inside of the filter housing using the same type of cleaner as used on the reusable filter element. Once clean and dry, you are ready to reassemble the filter unit, lube the quad ring with oil, and reinstall.

A spare seal is included in with the filter, spare can be purchased later if needed, they can be used a few times before replacement is required, If you have any further questions please do let me know.

Kind regards Jason

Micronic oil filter.

I have got a Middlebridge Scimitar (what) fitted with a modified 2.9 Ford Scorpio engine. It was built 5 years ago and has done 52K miles since. It is stage II tuned and develops 210 BHP. As such the oil can get a bit warm.

Will this product fit this engine? Is it suitable for the older type engine? Have you any way of knowing roughly what oil temperature reduction it will achieve? The oil filter cannister on my engine is fitted horizontally to the engine and points towards the inner wing. So I need to know how long your product is please to make sure there is enough room for it to fit. Assuming that your product is suitable, I intend keeping the car for many years. As such do I need to purchase spares to go with the unit ie rubber seals/springs? One last question. How do you clean the filter out.



Many thanks to Peter for this wicked upgrade which has improved his oil pressure and improved the filtration system on his Middlebridge! I do intend to purchase and fit one of these wicked filters to my Middlebridge. Mick ;o)

May be the last oil filter you'll buy
'Inspect, Clean, Reuse'
Unique Design, Top Quality Materials and Construction
The K&P Engineering filter element is made from medical grade, type 304 stainless steel micronic filter cloth to provide unmatched protection against oil contamination and resultant engine damage. A one inch square of this material flows an incredible 1.9 gallons of oil per minute at only 1 PSI pump pressure. The adhesive used in the filter assembly process is good to 600 degrees Fahrenheit, far above normal engine operating temperatures. A super strength nickel-plated neodymium rare earth magnet is installed in the top of the element for magnetic pre-filtering of the oil. The sophisticated bypass is engineered for proper differential pressures and consistent operation, delivering a greater percentage of filtered oil while being very easy to clean. The twist lock design assures positive filter element placement and allows for easy disassembly, inspection and cleaning. The quad-ring gasket doubles the seal between the filter and the engine. Finally, the filter housing is carved out of a solid chunk of 6061T6 billet aluminum, which not only looks trick but aids in dissipating heat.

  • Cleanable and Reusable
