A Quick Look at OE Match
OE Match information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.
Choosing the Right Fit for Your Porsche
Where OE Match is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Often chosen when owners want OE-equivalent quality with sensible running costs, especially for routine service and wear items.
- Typical reasons to replace include restoring reliability, addressing age-related wear, or refreshing multiple components during larger repair work.
- Common defects from incorrect application include noise, premature wear, leaks, or fitment quirks if the wrong variant is selected or fitted with old seals/hardware.
- Watch for symptoms such as unusual noises, early wear, or repeat failures after recent work, which can indicate mismatched parts or supporting items left worn.
- Always cross-check OEM part numbers, read model-year notes, and verify compatibility before ordering.
- For safety-critical components, confirm specification and fitment carefully and have installation checked by a competent technician.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include vibration under braking, longer stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.
Brake Pad Wear Sensors — Brake pad wear sensors are replaced when pads are renewed or when warning lights indicate a broken or worn sensor. Symptoms include brake wear warnings even with new pads, damaged sensor cables, or broken clips around the caliper area.
Engine Electrical — Engine electrical parts are changed when there are starting, charging, ignition, or sensor-related faults that affect drivability and reliability, such as intermittent no-start, misfires, rough idle, poor charging, warning lights or heat-soak failures.
Service Parts — Service parts are replaced as routine maintenance to keep the engine and systems reliable, efficient, and protected, often resolving hard starting, rough idle, poor fuel economy and warning lights caused by clogged filters or worn ignition components.
Service Kits — Service kits bundle key service components to simplify maintenance and set the car back to a known baseline, especially useful when catching up on overdue servicing or dealing with general sluggish running, inconsistent idle and reduced performance.
- For brake parts, confirm whether items are OE-equivalent replacements or performance upgrades and check if new fitting kits and sensors are required.
- On service items and kits, match the kit to your exact Porsche model, engine and year, and review what is included so you can add any extra “while you are there” parts.

This OE Match cylinder head stud is a replacement engine fastening stud for Porsche 911, 964, and 993 models from 1965 to 1998. It is designed to match the original-style fitment and function, helping secure the cylinder head and cylinder assembly correctly to the engine crankcase.
Sold individually, Normally 24 studs per engine
Fits:
Porsche 911 1965 - 1989
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998
This product supersedes Porsche's old part numbers:

The cylinder head stud provides the clamping force needed to hold the cylinder head, cylinder barrel, and engine case together. Correct head stud tension is essential for maintaining combustion sealing, cylinder stability, and reliable air-cooled engine operation.
Functions
• Secures the cylinder head and cylinder assembly to the engine case
• Provides correct clamping force for combustion sealing
• Supports cylinder and head alignment
• Helps maintain reliable engine sealing under heat and load
• Replaces corroded, stretched, broken, or damaged original studs
• Suitable for engine rebuilds, top-end repairs, and head stud replacement
• OE Match replacement for classic Porsche air-cooled engine repair
Why Replace This Part?
Cylinder head studs are exposed to high combustion forces, heat cycling, corrosion, vibration, and long-term engine load. Over time, studs can corrode, stretch, weaken, seize, or break. A damaged or broken head stud may cause compression leakage, oil seepage, cylinder head movement, exhaust leakage, poor running, or engine noise. Replacing worn or failed studs helps restore proper engine clamping and long-term reliability.
When to Replace This Part
• A cylinder head stud is broken, corroded, stretched, or damaged
• The engine has compression leakage or cylinder head sealing issues
• Oil seepage or combustion leakage is present around the cylinder/head area
• The engine is being rebuilt or overhauled
• The cylinder heads or barrels have been removed
• Existing studs are seized, heavily corroded, or unsuitable for reuse
• Preventative replacement is being carried out during top-end service.
Where it fits on the car
This cylinder head stud fits within the engine crankcase and extends through the cylinder barrel and cylinder head assembly. It forms part of the engine’s main cylinder/head fastening system and should be installed according to the factory engine layout and torque procedure.

Dilavar engine head studs are specialized fasteners used in the engines of certain Porsche models, especially air-cooled engines (like the 911). They are made from a proprietary alloy called Dilavar, which is designed to address specific thermal expansion and durability challenges in high-performance engines.
Price is each. Normally 24 studs per engine.

Solves the problems of loose head studs, The exhaust leak you hear in the 911 may actually be the cylinder head leaking where the studs have pulled loose. As Porsche increased displacement of the 911 engine, the different rates of thermal expansion have caused head studs to break or pull out from the engine case. These latest Dilavar steel head studs have a thermal expansion rate of approximately the same as the alloy case.

This OE Match intake manifold rubber sleeve is a replacement rubber connecting sleeve for Porsche 911 and 914 models. It is designed to match the original-style fitment and function, helping provide a secure air intake connection within the engine induction system.
Fits:
Porsche 911 1965 - 1973
Porsche 914/6 1970 - 1972
Diagram ref no 6/1
The intake manifold rubber sleeve helps connect and seal sections of the intake manifold or induction system. A good sleeve helps maintain correct airflow, prevents unwanted air leaks, and supports smooth engine running, correct mixture control, and reliable intake system performance.
Functions
• Replaces the intake manifold rubber sleeve
• Helps seal the intake manifold connection
• Supports correct airflow through the induction system
• Helps prevent vacuum leaks and unmetered air entry
• Supports smooth idle and consistent engine performance
• Replaces cracked, hardened, split, loose, or perished original sleeves
• OE Match replacement for classic Porsche intake system repair.
Why Replace This Part?
Rubber intake sleeves are exposed to heat, fuel vapour, oil mist, vibration, and age-related deterioration. Over time, the rubber can harden, crack, split, shrink, or lose its sealing ability. A failing sleeve may cause vacuum leaks, rough idle, poor running, hesitation, difficult starting, or incorrect fuel mixture. Replacing the sleeve helps restore a secure intake seal and dependable engine performance.
When to Replace This Part
• The rubber sleeve is cracked, split, hard, loose, or perished
• Vacuum leaks are suspected around the intake manifold
• The engine has rough idle, hesitation, or poor running
• Intake manifold parts have been removed or serviced
• Fuel injection or carburettor components are being inspected
• The intake system is being rebuilt or restored
• Preventative replacement is being carried out during engine service.
Where it fits on the car
This sleeve fits within the engine intake manifold / induction system on Porsche 911 and 914 models. It is used at the intake connection point where a rubber sleeve seal is specified.
