DO I NEED A NEW MASS AIR SENSOR WITH THIS

you use the factory one. a tip: drill a hole to relocate it closer to the throttle body, this way you do not have to use the extension harness the kit comes with(mine didnt work) and then plug the hole that it came with, with a rubber bung

No you do not. Ive had mine in place for a few years now without a sensor and everything's running great!

No you have to use the factory mass air from your factory filter box carefully dismount it and then mount it in the new filter the instructions take you step by step in how to install it, hey it work great

No sensor included. If you do your own brakes, just monitor how much pad you have left and change it before the sensor gets tripped if you want to save a few extra bucks. MB sensors are not too expensive. BMW ones have a long wire attached and it runs like $30 to replace, ouch!

No, just received my pair in a box with the wiring. Had the lame air pillows in the box, but plenty of room to move around. The sensors are just in little plastic bags. I was changing them as a preventive maintenance, because my 5.3 Intake Manifold gaskets failed. Does anyone know if they can be tested before installing them? I'm paying a mechanic to do the work. Really don't want pay for the job twice, because Amazon does not know how to ship fragile items.

You got 4 sensors and every sensor is a different part number so you would need each individual sensor in the wright place or your check engine light will go on. Hope this helps.

Just because you have an o2 sensor code it does not always mean the sensor is bad. You may have a problem with the wiring or an exhaust leak

I was told that some cars had different front and rear sensors. My car had California emissions so they were different. Talk to auto parts store first.

You do not need to purchase two. If your system only has one sensor that's all you need. In my case, the water sensor failed and this item replaced it perfectly. My system's original air sensor is still working fine and I expect it will for a long time as it is sheltered from the elements.

Sensor must be removed to add air.So you must unlock to add air.I never use them . PitBoss.

If your existing sensor looks identical to this one it should. I would contact and ask the seller to be positive.

sorry for the delay. As I understand the sensor if you have a built in sensor you do not need this one

I can't answer your first question but mine does have a vacuum sensor...I suggest you pull your old one and see if you can get a part number...That's how I found this one. Very easy to remove/install...3 or 4 screws and the leads and of course the vacuum.

There is a website at the back of the manual. But personally, I would just replace the whole set. One sensor cost around $30-$50. If one sensor dies, then you have an idea that the 3 sensors will follow. You might as well replace everything, plus you can save money to put them in.

You don't need a new front sensor and a new rear sensor for safe brakes...but you need new sensors to make the brake warning light go out. Only one in front and one in rear. After service and new sensors just leave the key all the way on at very last click before start. Leave it on until brake warning light goes out.

Take your original part and see what Denso says is the actual replacment model number for your cars' air fuel sensor. If Denso gives you a part number as a cross reference-it's probably good. Just go to the Denso website and punch in your old part number (the old one that came off the car.) Otherwise go to the dealer and get the actual part number from them at the parts department for your car. You could use that number to see what Denso says. Good Lucks

No. Part of the installation is transferring the mass air flow sensor the factory intake to the K and N.

I did reset mine but I probably didn't need to. I also covered the sensor with a piece of tape.
