About Silverlake

Silverlake for Porsche

Silverlake parts for Porsche models from Design911.

A Quick Look at Silverlake

Silverlake 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 Silverlake 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.

  • Typical reasons to choose these parts include restoring reliable function on common Porsche repairs and keeping the car dependable for regular use.
  • Common issues they are used to address include noise, looseness, leaks, or intermittent operation depending on the component, often after other parts in the system have worn.
  • Watch for repeat failures caused by incorrect application, skipping seals or consumables, or leaving worn supporting components in place.
  • Before replacing, confirm the root cause of the symptoms, as problems can point to wider system faults rather than a single failed part.
  • Where applicable, replace related seals, gaskets, and hardware at the same time to reduce the risk of future leaks or rework.

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 changed during a planned rebuild or when symptoms point to internal wear such as loss of compression, heavy oil use, persistent leaks, abnormal noises, or contamination found during inspection. On Porsches, many owners take the opportunity to renew bearings, chains, guides, seals, fasteners, and gaskets while the engine is apart so labour is only paid once and reliability is improved after the rebuild.

  • Carry out compression and leak-down tests, inspect bores with a scope, and check the oil/filter for debris before committing to a rebuild.
  • Plan to replace hard-to-access wear items "while you’re in there" to avoid another engine strip-down later.

Exhausts — Exhaust components are replaced when corrosion, leaks, rattles, or blocked catalysts affect performance, noise, or emissions, or when owners want to change the sound and back-pressure characteristics. For Porsche applications, the choice of system usually balances desired tone, drone levels, weight, compatibility with emissions equipment, and whether the car is road or track focused.

  • Inspect for blowing noises, soot marks at joints, broken hangers, or MOT/emissions warnings as signs an exhaust section may need attention.
  • When changing exhaust parts, budget for new gaskets, clamps, mounts, and any rusted fixings to avoid leaks and future issues.

Manifold / Headers — Manifolds and headers are changed when they crack, leak at the head or joints, or when upgrading for better exhaust flow and reduced weight. On Porsche models, snapped studs and heat-related fatigue are common, so replacement often focuses on durability, correct fitment, and gaining response or power when combined with matching exhaust components and tuning.

  • Listen for ticking on cold start, check for soot marks around flanges, and look for snapped studs as indicators that manifolds or headers require attention.
  • Always renew gaskets and damaged studs/nuts, and consider suitable heat shielding or wraps where temperatures are high.

Heat Exchangers — Heat exchangers are replaced when rust, cracks, or internal leaks affect cabin heat output or allow exhaust gases to escape. On air-cooled and some classic Porsche setups, owners often choose updated designs or materials to improve corrosion resistance, maintain good heating performance, and ensure safe routing of exhaust gases away from the cabin.

  • An exhaust smell inside the cabin, poor heater performance, or visible corrosion around the exchanger are key signs to investigate immediately.
  • Check heater ducts, control flaps, and exhaust sealing surfaces at the same time to make sure the whole system is sound.

Exhaust Nuts / Bolts / Studs — Exhaust fixings are routinely replaced because they corrode, seize, or snap during removal, especially on older or high-mileage Porsches. Using fresh, high-temperature hardware helps restore correct clamping force, maintain gas-tight joints, and make future servicing easier with less risk of broken studs and leaks.

  • Even if old hardware appears serviceable, repeated heat cycles can weaken it, so new nuts, bolts, and studs are recommended during exhaust work.
  • Use appropriate anti-seize and heat-resistant, self-locking or copper nuts where specified, and torque to the correct values.

Fuchs Style Blank key.
Available in PVD Black, Clear, Brass and Titainium

silverlake

Fits
Porsche 911 1970-1989
Porsche 914 1970-1976
Porsche 964 1984-1994
Porsche 993 1994-1998

Fuchs style CNC machined key blanks for your air-cooled Porsche 911. Available in different materials, raw or PVD coated for protection and decorative purposes.

These key blanks are machined from 303 stainless steel bars – the same material used in the factory keys

Black key blank is PVD coated for protection and decorative purposes

Note: Some subtle machined tool marks maybe evident on the surface of the key bows. We personally like the finish, and did not polish/sandblast them, as it reflects the CNC machining process behind the keys.

Note 2: Stainless steel and brass key copies can just be made in your local hardware store. Titanium keys require applying multiple slow passes with light pressure on a manual machine, until all teeth are completely copied. After demurring with the usual wire wheel, additional use of a piece of sandpaper (200-320) is needed to smooth the sharp edges left from the cutting process.
