The easy way to do a "golf tee" mod
1. Take 1 x $0.50c plastic spring clamp
2. Bend and clamp vacuum hose.
- It took me all of 10 seconds to reach under there and clamp the hose. I didn't even have to look under the car.
- It's removable in seconds.
- It's held on without falling for 10,000km, track day, 200kmph+ speeds.
- There's no risk of codes, unblocked vacuum hose, anything breaking, etc.
