Product Overview
About the Mantis MTP-1021 1.8T 20v Performance Ignition Coils.
The legendary VAG 1.8T 20v, sparked properly – in the car it came in, or the one you swapped it into.
The 1.8T 20v is one of the great tuner engines – Golf GTI Mk4, S3 8L, Leon Cupra R, TT 180/225 – and twenty years on, most are running tired original coils. Big-turbo builds, chipped daily drivers and stock cars alike all show the same first symptom: misfires under boost and lumpy cold idle.
It’s also one of the most-swapped engines in Europe: Mk1 and Mk2 Golfs, Caterhams, Westfields, kit cars, buggies and track specials all run transplanted 1.8Ts – and a strong, reliable spark matters even more in a swap. The Mantis MTP-1021 is a direct replacement for the 06B coil, engineered around a neodymium core delivering 12% more spark energy than standard OE coils – with the headroom K04 hybrids and big-turbo conversions demand.
