Distributor Block-Off & Conversion Kits for Classic Porsche 911
The Distributor Plug Kit for classic Porsche 911 covers the
precise scenario where the engine’s original distributor hole is no longer
used—often when converting to coil-on-plug ignition or eliminating the
mechanical distributor altogether.

Blanks off distributor hole in crankcase, highlighted in green
This high-quality kit is CNC-machined from aluminium, anodised silver, and features dual O-ring seals to ensure a secure, leak-free block-off of the distributor housing. It also incorporates a threaded pulling hole so the plug can be removed easily if future service is required. The result: a clean, visually refined engine bay appearance and a reliable closure of the distributor port, preserving oil-tight integrity and engine performance.
What the product is:
A
plug kit designed specifically for the distributor bore in classic Porsche
911 engines.
CNC-machined
aluminium block-off plug, enhanced sealing (double O-rings), and
serviceable pull-thread.
What it does:
- Seals the distributor aperture when the mechanical distributor has been removed or bypassed.
- Maintains crankcase oil integrity, prevents leaks and contamination ingress.
- Enhances engine bay aesthetics by replacing the open distributor hole with a tailored, polished plug.
Why the original part or configuration fails / needs
attention:
When
a distributor is removed (for example during coil-on-plug conversion), the
hole becomes an unsealed opening—risking oil leakage, contamination
ingress (dirt, moisture), crankcase pressure loss, or aesthetic
degradation.
Older
distributor seals and housings may become warped, cracked or worn with
age, causing leaks or reduced reliability.
Why this plug kit should be installed / replaced:
- Prevents oil leaks and contamination by securely sealing the engine block in the absence of a distributor.
- Improves engine bay appearance and presents a quality finish.
- Provides a service-friendly solution (threaded pull hole) versus a crude blanking plate or crude cap.
- If
you’re converting away from a distributor or refurbishing the engine,
installing this kit is a simple, low-cost upgrade to protect longevity and
maintain engine integrity.
For enthusiasts of the classic Porsche 911 who are performing engine conversions, refurbishments, or upgrades, the Distributor Plug & Block-Off Kit category is essential. These kits are designed for scenarios where the factory mechanical distributor is removed—commonly in coil-on-plug conversions, performance builds, or restoration projects.
What these components do:
- Securely blank off the distributor aperture to maintain crankcase integrity.
- Prevent oil and vacuum/pressure leakage from the engine block.
- Ensure that modifications (such as eliminating the distributor) do not compromise engine performance or reliability.
- Provide a finished, professional engine bay look—no open holes, no unsealed ports, and no risk of contamination.
Why you should replace or install proper kits now:
- Restores or maintains crankcase seal integrity, protecting engine internals from oil and debris.
- Helps maintain correct engine pressure and lubrication environment for optimal performance.
- Minimises risk of leaks, contamination, and subsequent engine damage—especially critical on high-value classic Porsche engines.
- Enhances presentation and value of the engine bay for restoration, show or performance builds.
- Using a quality kit from Design911 ensures you’re installing parts that meet or exceed the factory fit and finish—and are tailored for your classic Porsche 911.
