That argument costs people a lot of money. We settle it on an ASNU flow bench with an integrated ultrasonic cleaner: every injector is flow tested, cleaned, tested again and verified before it goes back in the car, with the numbers on paper.
Port and direct injection, factory and aftermarket, from a rough idling daily to a set of ID1050x injectors going into an E85 build. Same day service in most cases: drop the set off in the morning, pick it up ready to go in the evening.
A set of eight, tested, ultrasonically cleaned, new filter baskets and seals where fitted, tested again. Before and after flow numbers included.
Same process on GDI injectors, which foul faster and cost far more to replace than to clean.
Other shops and dealers send us injectors. Trade pricing from $240 a set for port and $300 for direct injection. Drop off or ship.
New aftermarket injectors flow tested and matched before they go in, so the tune is not chasing a lazy cylinder.
Rough idle. A misfire on one cylinder that moves when you swap coils. Poor fuel economy. Hard starts on a car that has been sitting. Lean trims on a datalog that no amount of tuning cleans up. A cylinder that reads different on the plugs.
Cleaning is a fraction of the price of a new set, and the flow sheet tells you honestly if one is beyond saving.
Yes. Bring or ship the set and we will test, clean and return them with the sheet. Same day service in most cases: drop off in the morning, pick up ready to go in the evening.
Yes. The bench does not care what the badge says, so any set is welcome.
Flow at several duty cycles for every injector, before and after cleaning, plus spray pattern and leak-down. It is how we prove a set is matched rather than saying so.
Especially there. GDI injectors sit in the combustion chamber and coke up. A cleaned and verified set is a fraction of the cost of replacement.
