Excellent
Great price, and excellent replacement spark plug for my old Mountfield SP470. Solved the starting problem straight away. Need to remember to change the spark plug every year.

Works well in old concrete mixer
Was not sure what spark plug to specify for an old side valve concrete mixer. Somebody had installed a racing plug in it that was unreliable. Briggs and Stratton say look for the model number (no chance on this well used machine). Decided on this short reach plug and it works well once the mixer is warmed up.

Long lasting and low cost
This is the spark plug recommended for use with my Briggs and Stratton lawnmower engine. It has proved more durable than the DIY store universal spark plugs that I used to use - and it costs less than half the price.

Replaced champion plug on Sovereign mower
Serviced the mower and wanted to replace the spark plug, oil etc. Googled the old spark plug part number QJ19LM and found this one was a compatible equivalent but it does have a different part number. Was good value and had good reviews so purchased. Easy to swap out and fit to mower. Started first time after service and has run well since.

OEM replacement - cheaper than aftermarket

Guter Originalartikel für kleines Geld...
Kostet in GB komischerweise nicht mal die Hälfte wie in D, ist aber ein B&S OEM-Artikel und funktioniert erwartungsgemäß einwandfrei.
