FSI/TFSI Audi/VW direct injection fuel injectors for sale. These are rebuilt, flow matched, and have better Teflon seals than OEM. They are serviced at 1,000 psi and then 1,700 psi in multiple ways/duty cycles. As most fuel injector rebuilders only test up to 6 bar/90 psi. Been running these in a lot of customers’ cars running higher than factory boost levels, or with boost added to normally NA engines from the factory, and just as replacement injectors for cars with high mileage that want to replace the injectors while doing a carbon clean or to solve misfires. The core charge will be refunded once I receive your old injectors back in good condition.
