ArchoilAR2810 Mass Air Flow Sensor Cleaner MAF, MAP, Air Intake Plenum and EGR Cleaner, 500ml, Residue Free Multi Action Formulation for Fast Results & Zero Waste. Professional Nozzle Applicator

Done the job , instant improvement

This product seems to have cleared years of oil deposits that had accumulated inside the air intake and on the throttle butterfly of my car.Using a scan tool to monitor the live data from my car, I found the throttle butterfly was only achieving 40% opening when accelerator pedal was floored.Test driving my car after use, I found the accelerator response was as when my car was s new. 😁Update to previous cleaning action removing the air inlet pipe leading to the throttle body, a seam of oil deposit was still present which required wiping away with paper towel saturated with the cleaning spray - without touching the butterfly plate.My throttle body is clean and the idle speed of my engine is more stable.

Does what it says on the tin

Really good. Does the job, came on delivery time and well packaged. Will buy again

Used this to clean my MAF sensor - I have a Bosch VAG sensor (used in probably tens/hundreds of VAG models circa 2004) and I was suspicious of an issue due to rough idling - everything else was fine with the car. Unplugging the sensor brought the car's idling back to normal so I was suspicious of the MAF sensor, having never cleaned it in the 9 years I've had the car.Before ordering a new Bosch MAF sensor (they're quite costly) I took my existing one out, and then removed the actual sensor carefully (attached with two special keyed torx type screws) - I gave the sensor a direct spray very carefully - notably the metal wire that does the sensing - very delicate area. I then gave the whole MAF enclosure a spray and clean too. If I'm honest not a lot of black dirt came out of my setup but once all reassembled, this rectified my idling issue. I was initially not able to see the wire clearly as it was coated in black slightly, but once sprayed and clean it was visible again - no doubt that was the issue.But trying to spray this sensor directly whilst attached within the MAF pipe enclosure would have been impossible and wasted a lot of this spray no doubt so ensure you've got your sensor disassembled and you're working directly on the sensor wires - but be careful!Saved me the purchase of a new MAF sensor and I'm convinced that this is the issue with most of you with idling issues - existing sensor just needs a clean, not replacement. And always good to start down that avenue.

No difference

I had to use it twice in succession to get the result I expected.

Good item
