Ignition Plug Gap Adjuster - Part Number BMS049

The BMS049 was a favourite in our workshop for setting plug electrode clearance quickly and consistently on turbocharged BMW petrol models from 2006 onwards. Built from CNC machined aluminium and engineered for accuracy, this USA made gap adjuster helped enthusiasts and professionals achieve repeatable results in minutes, protecting electrodes while dialling in the exact clearance required for tuned and stock applications alike.

We have used this unit in house for years and our customers loved the speed, precision and simplicity. If you’re chasing smooth idle, strong spark under boost and reliable ignition performance, a proper gap setting tool is essential.

Why owners loved it

• Fast and repeatable electrode clearance adjustment for reliable ignition under boost
• CNC machined aluminium body for durability and accuracy
• Accepts the common 12 mm and 14 mm plug thread sizes used across many 2006+ turbo BMW petrol engines
• USA made workshop grade tool designed for tuning and maintenance

Use with feeler blades for pinpoint accuracy
