FAQ
Do I need to replace all six injectors at once?For best balance and performance, we recommend a matched set. However, injectors are sold individually if you’re replacing a single failed unit.
Will these work with a stock CP3 and turbo?They can operate on stock systems, but to realize full 250HP potential you should pair with adequate lift-pump supply and an upgraded turbo/tune.
Is tuning required?Tuning is strongly recommended to optimize fueling and drivability with higher-flow injectors.
What about emissions?Higher-flow injectors are intended for off-road/competition use where permitted. Check local regulations before purchase/installation.
