MAF Replacement
 

I have a CEL code that says I need a new MAF.
Who was the OEM for the 1998 Boxster?
What brands are recommended and available today?

You can buy an oem sensor (made by Bosch) from a dealership at $600 plus, or Bosch equivalent at $250 plus. Some have suggested that the Bosch sensors vary in terms of quality control however. In the past I found an excellent aftermarket sensor for $89 - that unfortunately is no longer produced.

I'm confused because my indy says his source is $320. Suncoast says $520. Pelican Parts says $87 rebuilt or $104. I know prices vary, but this is too much of a variation.

Schellman, when I looked up the Bosh MAF's on Pelican I found prices ranging from $236.25 to $254.25 (depending upon year) - and remember, these are Bosch OEM and not from the Porsche parts catalogue. Suncoast sells only Porsche parts.

Bosch makes the MAF sensors for Porsche. If you buy an MAF sensor from a dealer expect to pay $600 plus. As an option, you can purchase what is essentially the same sensor from Bosch at a fraction of the price (for a 2.7 around $225 to $250) . The only criticism that I have heard about buying the Bosch sensor, is that quality control can fluctuate depending on what factory the sensor was made in. Apparently, Bosch has numerous factories of their own around the world, as well as they out source from other manufacturers too. Personally, I've not heard of anyone receiving a bad Bosch sensor. And, in most cases a seller should honor Bosch's 12 month warranty.

wow
whole new car

I would go with the Bosch part. I bought an aftermarket for $100 and while it works, it's not right on the button according to the o2 sensor readings on the dura metric. If I had to do it over again, I would pay the extra and get the Bosch.

I was under the impression that a MAF sensor either worked or it didn't . Please explain ?

The Fuel trim is about 2, which is within the range but outside of the spec. With the old failing Bosch MAF, the values were about -1, so I doubt the problem is a vacuum leak or other problem. My theory is the aftermarket MAF is under reading the air and the DME is compensating by enriching the mixture, thus leading to the + values on the Fuel trim values.

RockAuto.com has the MAF for your Boxster (BOSCH Part # 0280217007) for $173.89. You can get another 5% off using code 164173797957921. Enter the code in the "How did you hear about us" line of the shopping cart.

I bought a Bosch one from them for my Boxster and it was perfect. Like others have said, it was a night and day difference in the cars performance.

Son of a *****!!! I ordered a new MAF from pelican yesterday with shipping was about $277. If I had waited a day I could of saved over $100. That sucks for me :ah:. Thanks for posting that for others though. Save some money folks!

Chuck, which year/model is that MAF for? I think there are 4 different ones between 1999-2004 from what I understand.

Installed new MAF and idle is rock solid but still showing high fuel pressure on gauge... Have only run the MAF for about 95 miles since Friday so maybe it'll take more to time to "learn" the correct AFR :confused:

I got the Bosch MAF for $240 through my local Carquest Auto Parts store. Called it in on my way to work and picked up on way home (no clue where they sourced it). Came in Bosch box and included 12 month warranty. Was nice to not have to wait on shipping and at least I can take it back to them to help if I have an issue.

Running like a new car, swear I got 20hp back...

Hi.
I put one in my 03 2.7 986 today, had it in my tool box for a month + now, but after reading this thread I decided to try the new one out even though my old one is still working fine.
Had a problem with my MAF and it put my engine managment light on, that was confirmed by a good independent Porsche garage about a month ago, the cost of a new one from a OPC would of been in the £100's so me being a tight bugger thought i'd cleaned it with carb cleaner first, and it's worked fine ever since, however when the engine management light came on last month I thought I might need a new one so I found this Maf on eBay:-
PORSCHE 911 996 997 BOXSTER 986 MAF MASS AIR FLOW SENSOR 0280218055 98660612500 | eBay
Item number 370874725806 cost £29.99p not sure how much that is in US Dollars.
Well took the car for a test drive and it drives sweet as anything, no idling problems, no miss fires, pleanty of power, in other words runs perfect.
I will be watching my fuel economy on the trip computer see what i'm getting now mpg as it was on 30.4/7 with the old one and that was on it's way out, will keep you posted when I've done a few more miles to get a good average read out on mpg.
The numbers on the mafs :-
Old one taken out was a Bosch one 986 606 125 01
New one in now has no makers mark on it but the eBay add gives the following:-
Porsche part number 986 606 125 00
Bosch part number 0280218055
Like I said working fine just need to keep an eye on mpg

Forgot to say they even give a 2 year warranty with it.
