Buying Ignition Parts for a 1985 Lada Signet
On this vehicle, the ignition system delivers spark at the right moment — plugs, coils, wires, distributors and ignition modules.

- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace plugs and wires (or coil boots) as a set — one weak cylinder makes the whole set feel bad.
