Product Number: 18328N
The WAI 18328N is a brand-new 12V 1.4kW PMGR starter motor. It is manufactured to HITACHI specification, replacing original-equipment units including HITACHI S114-481, S114-481A, S114-808, S114-808A and S114-808B. It is designed to fit Vauxhall and Opel applications — including the Vauxhall Vectra and Opel Astra — covering six confirmed applications across both marques.
Built to the PMGR (Permanent Magnet Gear Reduction) design, this starter delivers reliable cranking through a compact, efficient motor topology that reduces current draw whilst maintaining strong torque output. The 11-tooth pinion and clockwise rotation are matched to the original HITACHI specification, ensuring the unit seats and engages correctly without modification.
With Lester reference numbers 18327 and 18328 both attributed to this unit, the WAI 18328N covers the full application spread associated with those indices. Fitment spans the 1991–2001 period for confirmed Opel and Vauxhall models, including diesel-engined Vectra (B) variants fitted with the X 17 DT (TC4EE1) 1.7 TD engine.

A. The WAI 18328N is a 12V, 1.4kW PMGR (Permanent Magnet Gear Reduction) starter motor with clockwise rotation and an 11-tooth pinion, manufactured to HITACHI specification. It carries Lester reference numbers 18327 and 18328. It is supplied brand new.
A. PMGR stands for Permanent Magnet Gear Reduction. This design uses permanent magnets in place of wound field coils and incorporates a gear reduction stage, which means the motor spins faster and draws less current than a conventional direct-drive starter whilst still delivering strong pinion torque at the ring gear. The WAI 18328N replicates the original HITACHI PMGR topology precisely.
A. This unit is listed under Lester reference numbers 18327 and 18328. Both indices are attributed to this starter motor and cover the same confirmed Vauxhall and Opel application set.
