Default How long did your MAF last?

After having something that seemed like fuel delivery problems I think I have come to the conclusion that the MAF went. The car has historically gone though an MAF every 12k miles, this latest one last a little more than 4000 miles. Anyone else have one go that quick? The only thing different is I put in a K&N filter recently, has anyone had that foul their MAF quicker?

So what are my options? $225 for a new MAF? Should I look into buying them in quantity to get a deal? Should I just fold and get a Tech II? How much are those running lately? Any other engine management systems that would rid me of that accursed MAF? Can you swap an MAF to a Subaru MAP with an ECU change from the same model?

Any other options?

stock intake except deleted silencer and drop in AMSOil filter, going strong since 4/99 and 35k miles on the clock.

didn't seem worth risking a $300 sensor to do an intake IMHO.

On a MY99.

Went to K&N Panel Filter in April 3, 2000 with 20969 miles on the car.

Went to RalliSpec intake in June 24, 2000 with 26600 miles on the car.

Cleaned the foam element (still in like new condition) on the RalliSpec intake on Feb 24, 2001 with 39088 miles on the car.

Currently at 48554 miles. And I still haven't cleaned the MAF.

----

Maybe I should sell my MAF when I go TecII eh?
(Asking price starting at $500 )

Default went thru 1 then bought a TEC-II

I blew one MAF a couple weeks after my turbo kit went on. I think it was related to the fact that the air filter would rub on the fender wall, sending vibrations thru to the MAF. Since moving to a short stack K&N I've had 6k trouble free.

RallyNavvie & DaveK - what kind of turbo kits did you guys go with? Every kit out there so far on the '99's except for the JCS ones have MAF problems

JC Sports IHI kit with ball bearing turbo upgrade.
I'm pretty sure it was related to the fact that the air filter didn't fit in the engine compartment well.

My 93 Turbo still has the original MAF with 153,000 miles. Works fine. I even have an extra 93 MAF...

could the 93 be retroed onto a 99? If so I think I can part with it.

So far as I know the MY99 is the only one that really has noticably more problems with its MAF. Rumors say it's because they aren't durable enough to deal with bumps and vibrations. Well that's gotta go for sure since I rally-x

Well guys, the '99 Mafs were all hot-flim... which is very flimsy vs. hot-wire. HOK has a Gen 1 JCS turbo kit w/ T28/T3 and he has had no MAF probs on his '99RS (it was turbo'd at 2000miles).

I've done 2 rally-xes and have had no problems with the maf, just make sure that you have it secured so it doesn't rattle around.
