Gold Leaf

Gold Leaf for Porsche

We are a team of mechanical engineers with a background in lightweight product design (composite manufacturing) and energetics (fluid dynamics). Needless to say, we are very passionate about automotive design and cars in general.Our goal is to produce highly engineered lightweight products for your Porsche with emphasis on increased performance, emotion and connection to the car at hand. All our products are researched and developed in-house, while also being hand made with utmost care. We are also design driven, therefore every product has a premium OEM+ feel and look, fitting perfectly in your precious vehicle.

Choosing the Right Fit for Your Porsche

Where Gold Leaf 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 compact, tidy installations that suit Porsche cabins and boots, plus extra peace of mind for classics, track-day cars, and vehicles with ageing fuel, oil, or electrical systems.
• Risk-related triggers rather than mechanical faults often drive upgrades – fuel smells or leaks, oil near hot components, older wiring, or circuit and track regulations.
• Common real-world symptoms include noticing fuel odours, signs of seepage, oil mist around hot areas, or simply recognising that aged components and more demanding use increase fire risk.
• Practical tips: mount safety hardware where it is quickly reachable yet securely fixed, follow the servicing intervals and checks specified by the manufacturer, and combine upgrades with preventative inspections of fuel lines and wiring.

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 planned rebuilds or when internal wear is suspected, such as loss of compression, heavy oil consumption, or persistent leaks and noises. On Porsches, owners often renew chains, guides, bearings, gaskets, and seals in one go while the engine is apart to avoid repeat strip-downs and to restore long-term reliability.

• Before committing to a rebuild, carry out compression and leak-down tests, inspect bores with a scope, and check the oil/filter for debris alongside diagnosis of ancillary systems.
• When the engine is open, it is common to replace chains, guides, tensioners, critical seals, bearings (where applicable), and hard-to-reach gaskets and hardware at the same time.

Air Intake & Injection — These components manage the air and fuel delivery that your Porsche engine relies on for clean combustion, power, and efficiency. Parts are typically replaced when you see issues such as rough or hunting idle, hesitation, misfires, poor fuel economy, or fault codes pointing to airflow measurement, vacuum leaks, or injector problems, or when upgrading for sharper throttle response.

• If you suspect leaks, a smoke test plus close visual inspection of boots, hoses, and joints is an effective way to locate issues.
• Injectors may be cleaned when flow is uneven, but leaking or out-of-spec units are often replaced to restore consistent running.

Airbox / Housings — Airboxes and filter housings protect the filter element and help ensure only clean, metered air reaches the engine. On Porsche models they are usually replaced when cracked, warped, or poorly sealed, when clips or gaskets fail, or after accident damage or unsympathetic modifications that cause unmetered air leaks, dirt ingress, or drivability issues.

• Alongside the airbox, it is sensible to renew seals and clips and inspect intake ducts and boots for cracks or poor fitment.
• A leaking or poorly designed housing can cause mixture faults and check engine lights due to unmetered air entering the system.

Engine Tuning — Engine tuning parts and calibration changes are used to refine drivability, throttle response, and power delivery, or to support hardware changes such as intake, exhaust, forced induction, or internal upgrades. Porsche owners also look at tuning when addressing flat spots, inconsistent boost, or poor cold and hot behaviour once mechanical health has been confirmed.

• Mechanical checks should come first: compression and leak-down, fuelling and sensor health, cooling and oil temperatures, and the absence of boost or vacuum leaks.
• Tuning cannot cure underlying mechanical faults; it should follow good diagnosis so that gains are reliable rather than masking problems.

Air Induction Kits — Induction kits are chosen to alter intake airflow, sound, and sometimes heat management, replacing more restrictive or aged factory components. On Porsche applications they are typically added as part of a wider tuning package, or when seeking sharper response and a more engaging induction note while keeping sensor placement and filtration appropriate.

• Good installation practice focuses on minimising hot air ingestion, avoiding unmetered air leaks, and maintaining stable MAF/MAP readings.
• Some kits mainly add sound rather than power, so it is important to balance expectations and consider remapping needs if airflow characteristics change significantly.
