Show original supplier description
The COBB Tuning 1300x² Fuel Injectors (3C1305) are engineered for high-performance applications, particularly those utilizing alternative fuels like ethanol. Constructed with an all-stainless steel internal design, these injectors offer exceptional durability and are compatible with all known fuels, including superior resistance to the corrosive nature of alcohol. Designed with versatility in mind, the ID1300x² injectors also accommodate the occasional need to revert to gasoline. They maintain a minimum fuel mass suitable for gasoline use, ensuring exceptional idle and cruise behavior even under these conditions. Each set is matched with a dynamic flow rate variance of within 1% and features a 14mm bottom O-ring. Data is supplied for tuning with COBB's Accesstuner Software. This kit includes six injectors and six adapters. The nominal flow rate for these injectors is 1335cc/min. **Vehicle Fitment:** Nissan R35 GT-R **Emissions Note:** This part is undergoing external testing with the EO process ongoing. It is NOT LEGAL FOR SALE OR USE IN CALIFORNIA ON ANY EMISSION CONTROLLED MOTOR VEHICLE. While compliance with EPA’s Anti-Tampering Policy is believed, the testing/CARB EO submission process has not been completed.
