Yes, I cleaned my MAF using this stuff and just drove the 968 yesterday. The difference was amazing, thus my enthusiasm for the product.
It comes in a spray can with the usual plastic nozzle. I set the MAF on my workbench and sprayed down through the plastic grid, then turned it up the other way and did it a second time.
The instructions say to do 10-15 short bursts onto the wire and venturi area. The solvent apparently dissolves and washes away anything that's accumulated on the area you clean, then the puddle evaporates in about a minute.
It is absolutely true that these things are very delicate. The hot wire itself is only .07 MM in diameter, so touching it with anything, even a Q-tip, is a very risky idea. The spray solvent approach eliminates any touching.
The immediate benefits I experienced are smoother idle and a more responsive throttle. The mfg claims more HP and better mileage, but I have no way to judge this, just a distinct 'buttometer' sensation of smooth power.
Last summer we replaced the MAF on my wife's Lexus and the change from cleaning the 968's MAF was very similar. In both cases, you can tell the ECU is getting a more accurate measure of air flow change as the throttle position changes. Said another way, you get the same amount of response with a more gradual throttle movement. On both her car and mine, it was a remarkable change.
So, bottom line, you'll love the difference and wonder why you never thought of this before.
