CRC MAF Sensor Cleaner

Sales Pitch: Safely cleans and protects mass air flow sensors

Description:
Most fuel injected vehicles are fitted with a mass air flow (MAF) sensor to measure air velocity which the computer uses to determine the proper air/fuel mixture. However, the MAF sensor gets dirty with debris, oil, grease and air filter fibres, causing inaccurate measurements of air flow which results in a 'rich' running engine, loss of power and excess emissions.
CRC MAF Sensor Cleaner will safely clean and protect your mass air flow sensor, improving air/fuel ratio and increasing kilometres per litre.
The use of aggressive products like brake and carburettor cleaners on MAF sensors can cause serious damage to sensitive parts.

Just a spray can. Remove sensor and spray??
Considering that I've moved from a oiled K&N Panel filter to an Injen CAI.
I was wondering if this would be worth a go?

Thoughts?

I saw that being advertised in the Repco catalogue yesterday.
Comes at about $16 a can though, so it's hefty, but if it's worthwhile then why not?

Same place I saw it. At A$16 a can, it's hardly costly. Though I'm not worried about that cost. IF you eff up your MFC, it's A$600 to replace. That's what I'm worried about.

CRC generally make good products. They are also generally safe from all the products I've used by them.

I do have a feeling this one is a gimmick though. I see no point in cleaning the MAF sensor, as if it is functioning, you should have a stable idle and stable air intake under load.

That's my opinion though. No facts to back it up.

ofey, it would depend on the type of maf sensor our cars are fitted with....

http://en.wikipedia.org/wiki/Maf_sensor

That Wikipedia site shows two principal sensor design types.
*Vane Type Meter (VAF) Old Technology.
*Hot Type Sensor (MAF) Latest Technology.

The most commonly found and used in current vehicles today is the Hot Type Design (MAF) which comes in two styles:
*Hot Wire (Platinum Wire)
*Hot Film (Nickel Foil)

Some of the benefits of a Hot Type Sensor ( MAF) compared to the older style Vane Type Meter are:
* responds very quickly to changes in air flow.
* low airflow restriction.
* smaller overall package.
* less sensitive to mounting location and orientation.
* no moving parts improve its durability.
* less expensive.
* separate temperature and pressure sensors are not required. (to determine air mass)

There are some drawbacks:
*dirt and oil can contaminate the hot-wire deteriorating its accuracy.
* installation requires a Laminar Flow across the hot-wire. (A design incorporated in the sensor that maintains the Air stream in a Fluid motion rather Turbulent motion)

I'm led to believe, the style used in our Lancers is the latest Hot Wire Type.

Sorry for bumping up an old thread, but can anyone who cleaned their MAF sensor comment on the best way to do it? Simply spray MAF sensor cleaner on the sensor, wait until it dries up and install?

Thanks!
