Delivery & Returns

Free UK delivery on orders over £75, otherwise £4.99. We order this in from our UK supplier when you buy it, so allow extra time before it ships. Once dispatched, standard UK delivery is 3–5 working days. Orders with filters or spark plugs have a £15 minimum — anything except merch counts towards it. You have 14 days to cancel; items must come back unused and in their original packaging — see our Returns Policy.
