图表参考编号 2（适用于 912）或 4（适用于 356）

该垫片提供正确的隔离和密封接口，确保化油器正确对准、端口匹配均匀，并防止热量从歧管渗入化油器。它采用耐高温材料制成，可复制原始设计并保持正确的绝缘性能。

该垫片非常适合发动机重建、进气维修或性能恢复，可恢复经典保时捷发动机可靠进气性能所需的预期间隙、端口几何形状和密封完整性。

随着时间的推移，原装垫片会因热循环、振动和燃油蒸汽的影响而老化、变形或破裂。受损的垫片可能会导致真空泄漏、燃油/空气混合比计量不准、怠速不均匀或性能下降。

在以下情况下更换此垫片：
•执行化油器或进气歧管维修或重建
•原有垫片破裂、脱层或缺失
•真空泄漏或怠速不稳表明感应密封存在问题
•将经典保时捷发动机恢复到出厂规格

安装新的垫片可确保正确的间距、适当的密封和真实的气流行为，从而确保发动机的持久性能和可靠性。

Complete intake manifold pipe, SET OF 2. 
Restore or upgrade the air intake plumbing on your classic Porsche 911 with this complete intake connection assembly. Designed for models with MFI/mechanical fuel injection, this intake pipe links the throttle/air-intake stack to the intake manifold, ensuring accurate airflow, reliable metering and correct fitment.

Fits:
Porsche 911 2.4 S / 2.7 RS 1972 - 1977

Diagram Ref No 12

What This Product Does:

• The intake pipe (or intake connection) is a critical component in the engine’s air delivery system: it connects the throttle body, intake stack or air intake system to the intake manifold of the engine.
• It ensures a smooth, sealed, correctly shaped passage of air (and in the case of injection, the air-fuel mixture) into the cylinder head, maintaining correct airflow, avoiding leaks or turbulence that could upset fuel/air metering or engine response.
• On the era of 911 referenced (MFI mechanical fuel injection), proper intake piping is important for correct function of the injection system, throttle response, and overall engine performance.

Symptoms Of Wear, Damage Or When Replacement Matters:

• Air leaks or a hissing sound around the intake pipe, which can upset the injection/air-metering system, cause poor running, unstable idle or reduced performance.
  
• Poor throttle response, hesitation or mis-firing — if the pipe is cracked, partially blocked, or has missing components, it can degrade engine performance.
  
• Cracks, corrosion, or broken mounting tabs visible on the pipe or its flanges — especially for older vehicles where plastic/metal parts have aged.
  
• Difficulty fitting or aligning connections between the throttle stack and manifold — if the pipe is out of shape or damaged, it may be difficult to achieve correct installation or clean sealing.
  
  

Why Replacement Matters:

• Ensures correct airflow and engine performance: A damaged or sub-standard intake pipe can compromise air delivery, disrupt mixture control, and reduce engine efficiency or driveability.
  
• Improves reliability: Old or worn intake components can lead to leaks, performance issues or even engine damage (if mixture is upset or induction temperatures become erratic). Replacing with a correct part restores the system.
  
• Simplifies installation: Buying a “complete” intake connection (rather than patching multiple smaller pieces) saves installation time, reduces risk of missing parts, and ensures compatibility.
• Ensures fitment integrity: In older vehicles, mounting points may have degraded—installing a new pipe with correct flanges/hardware ensures everything aligns properly, reducing stress or potential leaks.

进气歧管垫片， 12 件套。
OE Match 替换垫片符合保时捷原厂规格，专为保时捷 911 Carrera 3.2L（1984-1989 年款）设计。该垫片可在进气歧管和气缸盖之间提供完美密封，确保空气和燃油精准输送至每个燃烧室。

适合:
保时捷 911 卡雷拉 3.2L 1984 - 1989
发动机代码：93020, 93025, 93026
请注意：不适用于 930 Turbo

图表参考编号 6。

•位置：进气歧管和气缸盖之间
•功能：密封进气通道，防止真空或增压泄漏
•更换间隔：在进气口拆卸、重建期间，或发生泄漏或怠速问题时
•优点：恢复气密性、平稳怠速和最佳空燃效率

使用 OE Match 93011019714 进气歧管垫片，让您的经典保时捷保持完美运转。它按照 911 Carrera 3.2 的 OEM 标准制造，将进气歧管密封在气缸盖上，确保气密性和高效性能。更换磨损或泄漏的垫片，即可恢复平稳怠速、强劲动力和原厂可靠性。

随着时间的推移，进气垫片会因不断暴露在热量、压力和燃料蒸汽中而变硬并失去弹性。

这可能导致：
•空气或真空泄漏影响混合平衡和怠速质量。
•功率降低、油门响应不佳或怠速不稳。
•可能出现稀薄运转并增加发动机磨损。

更换期间：
•进气歧管拆卸或维修。
•发动机重建或顶端大修。
•任何时候检测到真空泄漏或空气燃料不规则现象。

更换 OE Match 垫圈可恢复正确的密封、稳定的怠速和平稳的动力传输 - 这对于保持保时捷的精确性能至关重要。

Inlet / Intake Manifold Gasket, SET OF 6.
Flat intake manifold gasket it used between the intake manifold runners and the cylinder head on Porsche flat-six engines. Each gasket seals one intake port pair; a complete engine typically uses six of them.

Fits:
Porsche 911 1974 - 1983  - 6pcs required

Diagram ref no 7.

This set of six intake manifold gaskets provides a complete gas-tight seal between the intake manifold and cylinder heads, ensuring that all air entering the engine follows the correct metered path through the CIS or fuel-injection system. By eliminating air leaks at the manifold flanges, these gaskets help maintain proper air–fuel mixture, support smooth idle and drivability, and prevent lean conditions that can raise combustion temperatures.

Over time, manifold gaskets naturally harden, shrink or crack from heat cycles, fuel vapour exposure and age. When this happens, the engine may draw in unmetered air, resulting in rough idle, poor cold running, lean mixture symptoms, hesitation or flat spots during acceleration. Vacuum leaks also make tuning more difficult and can lead to increased fuel consumption. Replacing old gaskets with a fresh set of six restores full sealing integrity, stabilises idle and mixture control, and helps the engine operate as intended.

When to replace
You should replace the full set of inlet manifold gaskets if:
• You are rebuilding or refreshing the top end of the engine.
• There are suspected vacuum leaks around the intake manifold.
• The engine shows rough idle, hunting, or lean-related symptoms not traced to other components.
• The existing gaskets are cracked, brittle, or oil/fuel soaked.
• You are upgrading, servicing or adjusting the CIS / intake system on a classic 911 or 930.
