OEM Mitsubishi Power Transistor Unit aka PTU
Sometimes when you are having ignition problems, it narrows all the way down to the actual ignition module.
If you are not getting any spark on any cylinder, this could be the culprit. This is a new OE replacement module (its located below the ignition coils).
Only for 1991-1999 DOHC TT and NA motors (not for SOHC engines).
** No warranty if not purchased WITH a new Ignition Coil Pack **
