If you're looking for a way to ensure your -AN fittings remain scratch-free during installation, consider using Exoracing adjustable AN wrench spanners. Due to the material used, traditional spanners often leave unsightly marks and scratches on the fittings. Anyone who has worked with -AN fittings knows how easily they can be marked.
However, with Exoracing spanners made from billet aluminium, you can rest assured that your fittings will remain pristine and your engine bay will maintain its top condition. Please don't settle for less than the best regarding your vehicle's appearance and functionality.
