Hi guys,

Decided to remove my LPG mixer ring today to see how much of a performance improvement there would be with less intake restriction. The mixer ring effectively restricts the throttle body from 65mm to 40mm. After removing the mixer ring, I'm left with a hole in the intake tubing. What's the best way to plug this?

Edit: All sorted. Bought a rubber plug for the intake hole and car now has noticeably more top end power on petrol.
