Has anyone tried CRC mass airflow cleaner? CRC is a well-established electronics cleaner brand, I've seen this stuff advertised recently and I think my NAPA carries it. I only believe the HP claim if the MAF is filthy, of course. Looking for first-hand comments on our hardware. Thanks...<p>Also thinking it might be a good solution to over-oiled K&N filters, btw.<p>Tom.<p><A HREF="http://www.crcindustries.com/auto/content/prod_detail.aspx?PN=05110" TARGET="_blank">http://www.crcindustries.com/a...05110</A><br><IMG SRC="http://www.crcindustries.com/catalog/images/Cleaners%20and%20Degreasers/05110.jpg" BORDER="0">

Other than an over-oiled K&N or BMC filter, why do you think you need to clean your MAF sensor? Speaking of 'oil' the claim on the can of HP gains seems like snake-oil to me.<p>LTA

If it's badly fouled and you clean it, you <I>will </I>get more HP and better mileage - but only back to where it should be, no "gains" to speak of.<p>Sniz had MAF fouling problems with his big cone filter intake resulting in rough running, uneven acceleration etc. After one replacment (I believe), I think he found cleaning it to be the cheaper/easier solution.

Re: Mass Airflow sensor cleaner (vizwiz)

Not sure. I mentioned a solvent/compressed "air" kit that VW sells as a possible solution and didn't hear back what he used, just that it worked.<p>Don't use a compressor though, they can build up a huge static electricity charge (not to mention too much air pressure) that could damage the MAF sensor or any electronic component if it finds ground.

Just loosen the clamps before/after the MAF body and pull the whole MAF and conduit out.

Re: Mass Airflow sensor cleaner (vizwiz)

Or.. I've used needle nosed vice grips in the past to grap hold of the screws on the sides and once out I suggest replacing them with standard.<br>

Re: Mass Airflow sensor cleaner (vizwiz)

5-point with security nub?? <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/screwy.gif" BORDER="0"> It's not like the secret to the universe is in there. Must be trying to keep them hamfisted non-Bosch-trained yo-yos out.<p>Anyway, can't you see the guts from the underside of the airbox? IOW, do you need to remove it to hit it with the spray?<p>Tom.

Re: Mass Airflow sensor cleaner (tmtalpey)

instructions call for drenching it pretty good, and repeatedly. not comfortable about letting all of that pool up closer to the intake. I'll try the flat blade trick, my new screwdriver kit is labelled and english AND german, so it must be high quality, right? LOL

You could also invest in these tools. <p>I've got this bit and some of his other tools as well and they are top quality, built to do the job.<br>Other tools are worth checking out as well.<p>The set may not be all you want, you can get the single bit if you want.<p>Check them out.<br><A HREF="http://shop.metalnerd.com/index.cgi?code=3&cat=5" TARGET="_blank">http://shop.metalnerd.com/index.cgi?code=3&cat=5</A> <p>Scroll down to see pics of set, the single bit is farther down.

Wow what a great site. He makes nice stuff. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <p>Tom.
