Every set of XS Injectors come with our exclusive and world first EXACT MATCH technology. Each XS Injector is grouped into exact matched flow rate and offset batches ensuring that each set has the lowest variance and highest performance available from any injector on the market. XS Injectors EXACT MATCH the flow rate to less than 1% in every set of fuel injectors to ensure the world’s best idle, cruise and startup performance. By EXACT MATCHing the offset (latency) to less than 2% in every set of XS fuel injectors, no other injector can match the sync of fuel to the injector pulse performance. No other performance injector testing comes close to the XS Injector’s dynamic flow matching process with over 6,500 flow testing points completed on each injector.
