Custom Spark Plug Tool for 718 4.0 engines, Thin Walled, Beats Porsche 918 721 900 61 Hazet 9006/1
Posted: Wed Dec 31, 2025 8:20 pm
This is a placeholder thread and an SEO test to see if I can create a venue for a 718 guy that has made a custom spark plug socket for the 4.0 liter engines for the 718.
For those "not in the know" Porsche, being more-Porsche-than usual, made the cam cover plug well for the 4.0 engine so small that only a super-thin walled plug socket can enter it. Even better it's at an angle so you have to use a u-joint or wobble extension. The special Hazet socket is available only from Porsche but it's Porsche-priced and not very good. And, yes, NOTHING else you can buy fits.
A gentleman on Rennlist started machining-down normal plug sockets to fit with a permanently attached u-joint and extension for less than the Hazet part.
A couple of folks bought the tool and loved it.
Last week he posted so see if there was more interest and he was - to put it mildly - banned. More like scorched earth the likes of which I've never seen in 25+ years on RL.
Hopefully by this time tomorrow googling for "custom plug socket 718" might find this thread?
