A proper look back at the David Appleby Engineering TR7 on the RAC Rally - driven by Mark Higgins with Carl Williams in the co-driver’s seat. This car became a favourite for one simple reason: it sounded incredible, and it performed just as well. We’re proud that an ITG air filter sits at the heart of the setup, keeping the engine breathing cleanly and consistently throughout the stages. Rally heritage, great engineering, and a team that knows how to make a TR7 sing. David Appleby Engineering Ro
