The highest PEA concentration is found in Redline SL-1, at least it was when I last checked. The only genuine chemical solvent that effectively dissolves carbon buildup and leaves no residual is PEA. PEA is present in Techron (concentration), but not as much. Nearly all other “fuel system cleansers” are essentially ineffective because they only use basic alcohols.
However, the top choices are:
Send your injectors to a trustworthy business that specializes in cleaning, measuring/balancing, and rebuilding (often using ultrasonic technology). They’ll return looking brand new.
2 – Replace your old Bosch Gen2 injectors with the more recent Bosch Gen3 injectors, which offer substantially better atomization and more uniform fuel distribution. My 325i DD doesn’t yet have them (100 percent upgraded brakes, suspension, and wheels, but I haven’t touched the drivetrain in terms of performance and don’t see the point in doing so), so I can’t say with certainty how much there is to gain on a stock motor. However, I installed them in my built/SC 328Ci and built NA M3.
Whatever path you take, I do suggest ordering/purchasing SL-1 and utilizing it frequently. It is very effective, and freshly cleaned or new injectors will continue to function perfectly.
After any “major treatment,” make sure to replace your gasoline filter; it’s a common maintenance task, but one that must be done.
Comparison of the benefits and drawbacks of the Nozzle Jet Fuel Injector Cleaning Kit
- Using a cheap aerosol cleaning chemical (we use CRC Clean-R-Carb), which is available on Amazon or at any nearby auto parts store.
- only draws energy from your car’s battery. No fancy equipment or pressurised air are required.
- single-person enterprise (no assistance required).
- The vehicle’s fuel injectors need to be taken out and cleaned.
- It is incompatible with BMW direct injection engines such as the N54 and N55, any diesel engine, or more recent twin-scroll turbocharged engines (it does work on the MINI S turbocharged engine which has port injection). Unfortunately, direct fuel injectors have a different plug arrangement and cannot be used with the tool. If these injectors are broken, they will require professional repair or replacement. If you are unsure of what kind of fuel injector you have, a good rule of thumb is that this gadget will not function if your vehicle has a BMW turbocharged or diesel engine.
Includes thorough part diagrams, part numbers, and links to buy all necessary parts to do this repair.
The 12V power line is linked to the injector’s electrical port. The solenoid valve in the nozzle opens when the current is turned on. The white tube is being cleaned while cleaning solution is flushed through it from liquid pressure in CARB cleaner bottles.
As was mentioned above, the fuel injectors must be taken out of your BMW or MINI’s engine in order to use the nozzle jet tool. On the majority of naturally aspirated (non-turbo) engines, this is actually a straightforward procedure and shouldn’t be at all daunting. For instructions on using the tool, please also watch the video at the beginning of this post.
- Organize the components of the fuel injector cleaning kit on a bench. Both the two power wires and the two plastic nozzles should have two different sized apertures.
- Select the plug and insert it firmly after making sure it fits your fuel injector.
- Select a plastic nozzle that has a fitting aperture for your fuel injector. Make sure the o-ring is securely inserted in the opening before installing the fuel injector into the nozzle.
- A 12V power supply’s negative terminal should be connected to the tool. The greatest option is the battery in your car.
- An aerosol fuel injector cleaner’s spray nozzle should be removed. CRC Clean-R-Carb is what we utilize.
- Incorporate the plastic nozzle of the instrument with the can of fuel injector cleaner.
- Push the aerosol cleaner’s plastic nozzle all the way down with one hand.
- With your other hand, tap the positive terminal with the tool while maintaining a firm downward pressure on the plastic nozzle on the cleaning can.
- Touch the positive terminal five to six times, each time for one second. To prevent internal solenoid damage, it is advised not to energize the fuel injector for longer than one second at a time. After a few trials, you ought to notice a difference in the spray pattern as the fuel injector is inside cleaned. Reassemble the engine and repeat the procedure for the remaining fuel injectors.

How much does a BMW injector cleaning cost?
You only need to conduct a fast online search on “fuel injector cleaning” to know there are an absurd number of goods and services available. A professional ultrasonic cleaner and tester can cost over $1000, while simple pressure “no injector removal” tools can be purchased for as little as $100. The choice is made even more difficult by the various opinions and reviews that are dispersed over car forums. Many BMW and MINI home mechanics give up and simply install new fuel injectors to avoid having to clean them at all.
This is the main point. You can clean your BMW’s fuel injectors just as well as any professional service for less than $20 if you know how to remove them from the vehicle (which is very simple for most models). Yes, $20 is exactly what you read. If you are a home mechanic working on your own vehicle, there is absolutely no need to invest in an expensive professional fuel injector cleaning kit. These equipment are excellent for repair facilities that clean hundreds of injectors annually, but they are not cost-effective for do-it-yourselfers working on a single vehicle.
How frequently should gasoline injectors be cleaned?
Thankfully, new gasoline slows down the accumulation in the fuel injectors. There are additives in the gas you put in your car, truck, or crossover to assist keep the fuel injectors clean. You can also purchase an over-the-counter cleanser to use sometimes. While these factors can lengthen the intervals between fuel-injector cleanings, they should never replace the cleanings themselves. Your fuel injectors may be partially clogged if you detect carbon buildup because neither the detergents in gasoline nor over-the-counter fuel injector cleansers completely prevent it.
- reduced fuel efficiency
- rocky starts
- pinging before ignition
- engine performance issues
- erratic idling
- slow throttle movement
By scheduling fuel injector cleanings in accordance with the advice of your vehicle’s manufacturer, you can prevent this. Generally speaking, a fuel injection cleaning should be performed every 45,000 miles or three years on any vehicle produced in 2004 or later. For the best engine performance in vehicles older than that, the fuel injectors may require more frequent cleaning. Professional cleaning will ultimately cost less because OTC cleansers must be used every 4,000 miles and those expenses pile up rapidly.
