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.
- 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.

Information
Seal set for intake manifold.
The set includes 12 intake manifold gasket pieces - enough to replace all applicable intake sealing locations when performing major engine or intake work on early Porsche. Intake manifold gaskets form the seal between the cylinder head and intake manifold. They prevent unmetered air leaks, maintain engine vacuum, and help ensure that the correct air-fuel mixture enters each cylinder.

Function When installed correctly, these gaskets:
• Seal the intake manifold to the cylinder head to prevent air and vacuum leaks
• Maintain consistent airflow into the intake ports
• Support stable idle and throttle response
• Reduce risk of detonation, poor fuel economy, and rough running.
Over time, intake gaskets may become brittle or compressed from heat cycles and age. Replacing them - especially in sets during rebuild or service - helps restore proper sealing and engine efficiency.
Intake manifold gaskets are critical for proper engine breathing and vacuum integrity. Worn, hardened, or leaking gaskets can cause:
• Vacuum leaks and unstable idle
• Hesitation or stumbling under acceleration
• Poor fuel economy
• Increased exhaust emissions
• Difficulty tuning carbureted or fuel-injected systems.
Replacing these gaskets in a complete set ensures all surfaces are sealed correctly, improves engine smoothness, and reduces the risk of running issues often misdiagnosed as other mechanical problems.
When to Replace. It’s recommended to replace intake manifold gaskets when:
• Performing major engine service or a cylinder head rebuild
• Intake manifold has been removed or loosened
• You notice hissing sounds or rough idle
• Vacuum gauge shows unstable readings
• Rubber/composite gasket surfaces show cracks, compression set, or distortion
• Engine has high mileage or long service life

本产品的作用：
- 进气管（或进气连接）是发动机空气输送系统中的关键部件：它将节气门体、进气管或进气系统连接到发动机的进气歧管。
- 它确保空气（在喷射的情况下，是空气-燃料混合物）以平稳、密封、正确形状进入气缸盖，保持正确的气流，避免可能扰乱燃料/空气计量或发动机响应的泄漏或湍流。
- 在 911 时代（MFI 机械燃油喷射），正确的进气管道对于喷射系统的正确功能、油门响应和整体发动机性能非常重要。
磨损、损坏或需要更换的症状：
- 进气管周围出现漏气或嘶嘶声，可能会扰乱喷射/空气计量系统，导致运行不良、怠速不稳定或性能下降。
- 油门响应不佳、犹豫或失火——如果管道破裂、部分堵塞或缺少部件，则会降低发动机性能。
- 管道或其法兰上可见裂缝、腐蚀或破损的安装片——尤其是塑料/金属部件已经老化的旧车辆。
- 节流阀组和歧管之间的连接难以安装或对准——如果管道变形或损坏，可能难以实现正确的安装或清洁的密封。
- 确保正确的气流和发动机性能：损坏或不合格的进气管会影响空气输送、破坏混合控制并降低发动机效率或驾驶性能。
- 提高可靠性：老旧或磨损的进气部件可能导致泄漏、性能问题，甚至发动机损坏（例如混合气紊乱或进气温度不稳定）。更换合适的部件可以恢复系统。
- 简化安装：购买“完整”的进气连接件（而非修补多个小部件）可节省安装时间，降低零件缺失风险，并确保兼容性。
- 确保配件完整性：老款车辆的安装点可能已损坏——安装带有正确法兰/五金件的新管道可确保所有部件正确对齐，从而减少应力或潜在泄漏。

进气歧管垫片在进气歧管和气缸盖之间形成紧密、无泄漏的密封。其主要作用是防止空气和燃油混合物泄漏，维持适当的真空度，并确保发动机运转时每个气缸都能获得正确的空气和燃油混合比。如果垫片密封不良，发动机可能会吸入未经计量的空气，导致运转不稳、油耗增加和性能下降。
安装在进气歧管和发动机缸盖之间的垫片：
•密封进气口，防止真空和压力泄漏
•保持适当的空燃混合气进入燃烧室
•降低外部泄漏的风险，防止污染物或高温气体进入不希望进入的区域。
•有助于发动机平稳运行，怠速稳定，油门响应灵敏，效率高。垫片采用优质材料制成，可抵抗经典保时捷发动机特有的高温、高压和化学侵蚀。
随着时间的推移，进气歧管垫片会因高温、振动和化学物质的作用而变脆、压缩或老化。当垫片失效时：
未经计量的空气会进入发动机，导致混合气过稀。
•可能出现怠速不稳和顿挫现象
•燃油消耗量可能会增加
真空泄漏会导致性能不稳定
更换磨损的垫片可以恢复正确的密封，改善发动机的整体呼吸，并有助于保持出厂规格的性能。
如果发现以下情况，请更换进气歧管垫片：
•怠速不稳或发动机性能不稳定
•燃油效率突然下降
•可见的真空泄漏或进气噪音
•在拆卸进气歧管进行维修期间
•发动机大修或修复

关于进气歧管
OEMatch进气歧管——流量、响应、精细化
OEMatch 为保时捷车型提供进气歧管配件，包括替换歧管、垫片和相关密封件，并附有详尽的交叉参考目录，以支持安装和维修。这些产品旨在帮助恢复稳定的气流和发动机响应，尤其适用于因进气歧管老化或损坏而影响性能的情况。
可用类型
- 铸铝进气歧管
- 复合材料/塑料进气歧管
- 歧管垫片和密封套件
了解 OEMatch 进气歧管
OEM（原厂设备制造商）零件是由生产您保时捷原装进气歧管的同一家公司制造的。
原厂配套 (OE) 指的是符合原厂规格的进气歧管部件，可能由其他制造商提供。售后市场部件则提供其他选择，有时具有更强大的功能或更高的性价比。OEMatch 提供非原厂配套的进气歧管，这些部件经过精心设计，可直接替代原厂部件，并按照保时捷车型的原厂规格尺寸和公差制造。
进气歧管本身将节气门体的进气分配到每个气缸，并有助于平衡压力和流量，从而实现平稳怠速和在整个转速范围内的稳定燃烧。
福利包括
- 恢复各气缸的均衡气流，实现稳定燃烧
- 改善油门响应和怠速质量
- 更换老化的密封件，以减少真空泄漏和排放
进气歧管磨损和失效的原因
- 热循环和材料疲劳会导致裂纹或泄漏
- 碳和油的堆积会限制管道和通道的通畅。
- 垫圈和密封件老化导致空气不受控制地进入
使用原厂匹配进气歧管的重要性
进气歧管泄漏或损坏会导致空气流量不均、发动机运转不稳和效率降低。更换损坏的歧管可以恢复稳定的气流平衡，有助于保护发动机部件免受过稀或过浓混合气的影响，并确保日常驾驶和检测测试中油门响应的稳定性。
优势
- 直接替换件，设计尺寸和公差与原件完全一致
- 提供配套的垫片和密封件套件，可进行全面维修。
- 采用耐热且密封耐久性高的材料制造
