So many engine options in these cars but just to clarify, Dave's has the 1.8 so it will be coil on plug IGN, thus no plug leads etc.
I note they have variable intake runners, appears to be vacuum operated.
Can Cruiserfield please advise if they have been known to stick or perhaps lazy in operation?
The system was on my old S13 Silvia with Ca18det engine.
Gave no trouble but a lot of junk for a very small improvement in that engine.
And as the Hyundai has VVT on both cams I can't see why they bothered.
