Tom,



Did you actually try this stuff? Did you notice any improvement in the way the car drives or idles?



I remember reading somewhere that it's extremely risky to try cleaning your MAF, due to the fragility of the wire. Hopefully this stuff is designed to reduce this risk. Anybody else out these have any experience with this cleaner? Thanks for bringing this to our attention.

Well CRC makes good stuff in my experience but I have not used this.

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.

Another vote of confidence for CRC MAF cleaner. I use it every time I clean and re-oil my K&N air filter element. Seems to drive smoother and respond quicker to throttle inputs each time. Good luck, Bob Blackwell.

I have had alot of success cleaning my MAF. I had an O2 sensor CEL, turned out to be a dirty MAF.

my car's running & idling really smooth(ly), great throttle response, so I'm wondering if I should just leave well enough alone ( 92,500 miles and as far as I know the MAF has never been cleaned ) or give it a quick spray of the CRC cleaner <img src="/forum/images/smilies/968/huh.gif" class="smilie" alt="" />



did not want to do anything to compromise those fragile wires, this puppy is not cheap ! looking online the prices are all over the board - from $ 300 for rebuilt to $ 740 for new at a "discounted price" , to $ 1,100 dealer price. YIKES ! WTF ? Are the wires platinum-plated gold ?



Oh, actually it must have a Porsche logo printed somewhere on the unit, so that would explain the cost <img src="/forum/images/smilies/968/dry.gif" class="smilie" alt="" /> .

Tom,



I'm glad this product worked so well for you. Was your car running noticeably badly before you used it? I'm asking because I feel a little like DS968, in that my car, though it has nearly 99,000 miles on it, idles smoothly, and appears to be running well, so I have some reluctance toward tinkering with the MAF wire, but on the other hand, I won't know how much better it could be running unless I try it. Since you also live in Austin, where did you find it? Thanks.

I've always used circuit board cleaner which is quick drying and leaves no residue. It definately keeps the car running smoother and should be considered a part of regular maintenance.

Another vote in favor. OK, I'll have to try it. Hopefully, the result will be like my clutch master/slave/high pressure line replacement, in that I didn't think there was anything wrong with the way my clutch was performing, yet the improvement in feel was dramatic.

I have a spray can of CRC electrical contact cleaner - is that the same thing ?



Ok, overlook my ignorance for a second and help a mechanically challenged dude out .. the MAF is inside the air tube section which has the plug going into it , right ( ? ) So, once you remove that segment you have the honeycomb plastic grill at both ends... then what ? What do you do ( undo ) next ? What gets sprayed ?

I use the CRC contact cleaner as well. It's the best I have found. I suspect it would work equally well on the MAF.

CRC contact cleaner is indeed good stuff ("QD Electronic Cleaner"), but I would never be caught without a can of Caig DeOxit Gold.

No, the part numbers are different. Maybe the two cleaners a similar chemically, but given the cost of an MAF, I wouldn't chance it.

Where can this stuff be purchased at?

I found it at Autozone, a very common item probably on the same shelf as the Carb/choke cleaner ...

got the CRC MAF cleaner at Kraegen auto parts ( Pep Boys did not have it ) so now if one of you guys can tell me how to get to the wires I need to spray, I'll be all set.
