Denso 197-6030 Mass Air Flow Sensor

OEM part. Easy install.

This worked perfect for my Toyota Corolla, selected this part number from Denso web site for my car model. Check Denso web site to make sure you order the correct part number.At first, I cleaned the exterior of the existing MAF sensor before removing it and waited one day to dry. This was to prevent any dirt going inside the hole while installing new one.When I got my order and installed the new MAF sensor, the engine started to run more smoothly, more powerful, there was a huge power difference before and after.I do NOT recommend to try to clean the old MAF sensor, that was the advice from my mechanic and I will do the same here. There is a rubber gasket at the perimeter of the sensor, even though you think you cleaned perfectly ( you can easily damage) ,old one can take air from the gasket and engine light will still be on , computer will get the air mixture wrong. Also there are inner tube wires to clean and it is not possible to reach and clean those wires, it will be a loss of your time and it may not work, long story short, buy a new one and see the difference in power.I believe this sensor should be renewed at every 50-80K miles to improve performance of your car.NOTE that immediately after the installation of new sensor, the engine check light does not turn off. It took me 30 miles of driving in two days, 4 cold starts to turn the lamp off. Mechanic said you can unplug negative then positive ends of the battery and reset the light ( be careful some cars you need to input radio codes when you unplug battery). Or you can go to your mechanic OR to an Autozone shop to reset the light, OR drive and wait for few days like i did.

One rainy day my Tacoma started up but shook like it was going to blow up or throw a rod. I was soooo bummed! Drove it to the shop 20 miles away. Two days later and $800 lighter, I got my Taco back. Mechanic said '3 hours of labor plus parts'. He replaced ONE coil, all the spark plugs, and the spark plug wires. I about popped a vein but that week was busy for me at my job so I didn't have time to do the work myself. So, I went on Amazon and bought three coils (yes, these are OEM Denso) and two sets of spark plug wires (OEM but priced at 60% less than the dealer). My Taco and my 4Runner (3rd Gen) have the same engines so the dealer had spark plugs at less than $3 each! Stocked up. Go on youtube and watch the 'how to change your spark plugs videos'. Super easy but make sure you have all the right extensions, nut drivers, sockets, and so on. Take. Your. Time. You do not want to mix up the wires. V6 3.7 L engines have THREE coils, not six and OEM coils easily last 200K miles and often go over 300k but if you're paranoid, change them the next time you change your plugs. It is NOT a three hour job but hey, all tradesmen seem to be pegged at $1000/day so if you want to save money, do it yourself. You need a torque wrench, a 'u-joint' adapter, metric sockets, extensions -- especially a 20-inch or so plus patience. Do it, you'll have a sense of satisfaction and accomplishment.

Tried to be cheap and get a different brand - what a mistake. It threw codes as soon as I installed it. Tried so many options to sort the issue with no luck. Then I bought this Denso and problem solved. Not a single code since doing so.Buy cheap you get cheap. This is worth it all day long.

I am elated with this part. It has been in my car about a week , now, and getting slightly better gas mileage. Before I purchased this I checked with the Toyota parts guy to be sure what is the correct brand of Mass Air Flow Sensor for my 2008 Prius. DENSO! My concern is this could be a cheap knockoff Chinese part, but, it sure isn’t acting like it. It took me about 35 minutes to install. Remove 2 screws and release the wiring harness. I used a screwdriver bit and a pair of pliers to remove and replace the 2 screws since there isn’t much room in front of the MAF. The dealer and my mechanic were asking me $225 just for the Denso part. I am hoping this is the real deal.
