TPI Iridium Spark Plug

NGK ZGR7GI-13G

The only spark plug we fit to TPI bikes.

Some KTM TPI models come from factory fitted with BPR7ES. Were not sure why as the 13G iridium plug give noticeable low end response with the spluttering.

The longer 14mm reach adds 1degree timing advance and 0.1 higher compression. This might not sound much, but the resulting low-end performance is noticeable especially when riding hard Enduro terrain where throttle response is vital.

NGK Laser Iridium spark plugs provide superior ignitability and long service life. Fine wire iridium tipped center electrode and fine wire platinum tipped ground electrode ensures slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions.
