About Ninemeister

Ninemeister for Porsche

Ninemeister parts for Porsche models from Design911, combining specialist Porsche knowledge with real-world upgrade and maintenance experience.

A Quick Look at Ninemeister

Ninemeister 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 Ninemeister 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 or position, and connector type where relevant.

  • Typical reasons people choose these parts include preventative maintenance on known weak points and building sharper, well-tested handling or performance packages rather than “cheap fixes”.
  • Common triggers for work include oil leaks, cooling issues, tired suspension or drivetrain bushes, brake fade, and repeat failures from non-specialist repairs.
  • Practical tip: diagnosis and parts choice are usually more accurate when a Porsche specialist is involved, especially on modified or higher-mileage cars.
  • Before upgrades, consider supporting changes such as alignment, tyres, fluids, and cooling to keep the setup reliable.

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.

Engine Rebuild Parts — Engine rebuild parts are typically replaced during a planned overhaul or when tests point to internal wear, such as loss of compression, high oil consumption, persistent leaks, abnormal noises, or contamination found in the oil. Many Porsche owners and specialists choose to renew chains, guides, bearings, seals, gaskets, and hardware together while the engine is apart to reduce the chance of repeat strip-downs and to restore long-term reliability.

  • Before committing to major work, carry out compression and leak-down tests, borescope inspections, and careful oil/filter checks.
  • “While you’re in there”, it is common to replace timing components, critical seals, and other hard-to-access wear items to future-proof the rebuild.

Turbo Chargers / Intercoolers & Parts — Turbochargers and intercooler components are changed when there is loss of boost, smoking under load, shaft play, or oil contamination in the intake system. On Porsche turbo models, keeping charge temperatures under control and pipework leak-free is key to consistent power and reliability, so owners often replace or upgrade these parts when chasing performance gains or resolving boost-related faults.

  • Because boost leaks can feel similar to turbo wear, pressure testing the system is an important step before replacing major parts.
  • It is often recommended to renew oil feed and return lines when fitting a new or rebuilt turbo to protect the investment.

Engine Tuning — Engine tuning work is usually carried out to improve drivability, throttle response, and fuel efficiency, or to match the calibration to hardware changes such as intake, exhaust, or forced induction upgrades. On Porsche engines, a sound mechanical base is essential; tuning is used to refine how the engine delivers its power, not to hide underlying issues like poor compression, unstable fuelling, or cooling problems.

  • Tuning cannot fix mechanical faults, so checks such as compression or leak-down tests, sensor data review, and inspection for boost or vacuum leaks should come first.
  • Reliability is maintained by pairing any increase in load or boost with suitable supporting modifications and conservative calibration.

Gearbox / Transmission — Gearbox and transmission parts are replaced when there are shifting problems, noises, leaks, or as part of a high-mileage refresh or performance upgrade. On Porsche models this can include clutches, synchros, bearings, mounts, linkages, differentials, or complete gearboxes, with the focus on selecting components matched to the specific transmission type and intended use.

  • Not all driveline noise or poor shifting comes from the gearbox itself; clutch condition, mounts, linkage adjustment and correct oil are all worth checking first.
  • Changing transmission oil to the correct specification is often a sensible early step when diagnosing minor shift quality issues.

Flywheel / Torque — Flywheels and torque converters are usually changed when there is judder, rattle, vibration, or evidence of heat damage, or alongside a major clutch or transmission service. On manual Porsche models, the condition and type of flywheel strongly influence drivability and noise levels, while on automatics and PDK-type systems the torque converter is central to smooth take-up and shift quality.

  • Dual-mass flywheels with excessive play or rattle are generally replaced rather than resurfaced to avoid damaging a new clutch.
  • Upgrading to a single-mass, lighter flywheel can sharpen response but typically increases drivetrain noise at idle and low rpm, something to consider for road use.

9m 718 2.0/2.5 spin on oil filter adapter kit

Spin on oil filter adapter kit specifically developed to eliminate any potential failures of the the OEM paper filter element which is prone to breaking down and the fibres of the filter and can cause fragments of the paper being sucked into the engine which will cause engine failure or faults that require engine strip down.

This kit is to adapt the standard paper oil filter cartridge to a conventional metal screw on canister filter setup.
Highly efficient and a huge improvement over the standard paper unit, providing much improved oil filtration.

Together with regular service intervals can prolong engine life.

Kit includes
Threaded spin on adapter plate constructed from clear anodized, 6082T6 aerospace grade aluminium and
 OEM type, high quality metal canister oil filter with built in pressure relief valve.

Easy to install - simply remove/unscrew the black plastic cone shaped original paper filter housing, and replace with/screw in our adapter plate. The new canister oil filter then simply screws onto the threaded nut in the centre of the metal plate no more messy oil changes draining from the plastic spout.

9m uprated billet aluminium 718 boost recirculation valve

Direct replacement for the  factory plastic replacement recirculation valve which are prone to leaking boost pressure and can cause boost back feeding through the inlet plenum which can cause failures.

Unlike a Blow-off Valve (BOV) which vents back-flowing charged air to the atmosphere, a recirculation Valve protects the turbo compressor from being stalled by redirecting the back-flowing charged air to the turbo inlet pipe.

Plug and play fitment 

Available in anodized black and red.
