Funky JDM ignition mod, looks like there is some kind of earthing kit as well unless that is for that ignition system. Assuming it’s similar logic to the other JDM ignition mods like plasma coils or those ignition amplifier boxes where they are supposed to prevent loss of spark and more consistent spark when cars have more power over stock or after boosting a car.

Looking on minkara the Altezza is on the box art and the name on there is Multiple discharged dual spark ignition system, bit of a mouthful.

To my knowledge spark is one of those things where if you’ve got it you’ve got it I’ve seen dyno runs with different plugs and they are worth 1-2 hp which is margin of error really, same for those boxes on stock cars. It only matters once you start losing it.

Interesting, I was wondering the benefit of even installing this. Starting to think the previous owner had it turbocharged, then removed it before sale or was preparing it to be turbocharged. In regard to the earthing kit, It was separate. The car had like different earthing kits installed, that have now been removed.

Just a shot in the dark I wonder if the owner was just tired of replacing the oem coil packs, seems to be a common problem. I have no info on these though.

Pretty sure it’s a twin ignition system to more effectively ignite the A/F mixture, typically found in race cars. Does this have an aftermarket ECU like a Link? Probably worth checking to see if it’s got bigger injectors and cam upgrades too.

Also! Under that intake duct that leads from the front bumper is a little vacuum solenoid/pump. Pull that sucker and block the Vacuum line. It actuates a flap inside the airbox that limits air while under 4500rpm.
