Thread: Alternators and MAFs

Hoges is right the OE part # is 1197311549 however the part on eBay is not OE equipment and I would hate to see any of you spend $20 on a questionable part. However I was able to find it at RockAuto for $51 and Summit for $58. Only thing I don'g understand is my alternator say's its a 130 amps not 150? In the short run I did decide to be the lab rat and found what was listed as a "new 150A" alt from a manufacturer in CA. I will rebuild my failed one and keep it for a spare and will let you know if the "new 150A" survives a year without failing.

My personal experience with MAF is to do as the other member suggested I clean it with MAF cleaner once a year and stay away far away from K&N filers. K&N filters are fine in carbonation vehicles but I personally would never use them in a vehicle with a MAF because the filter's oil blows onto the sensor and causes the poor starts, jerky acceleration like you have a dirty fuel filter, poor performance, and gas mileage. Years ago before I learned of the MAF cleaner I decided to be cheap and buy a after market MAF on eBay for my 1995 BMW 540 and the car never ran the same and couldn't return it. Then I had to shell out the $350-400 to buy a new one. Looking back if I were in the position again I would have picked another one up in a salvage yard and saved the money and the hassle.

g'day 00 Disco II and welcome to the forum!

You're correct, the part I got from ebay ..Wenzell's garage somewhere in rural USA if I recall... is not OEM for the simple reason that Bosch do not supply them other than in a brand new alternator ... in every other respect however, including 'manufacturing marks' the substitute is an exact replica of the original and works very well indeed! You are most fortunate to have access to a competitive market where techie stuff is available at reasonable prices! Enjoy your LR experience..it can become addictive

There is a firm in the states selling COMPLETE new units they make themselves for a very good price, I think they sell on e-bay
The 150 amp from the P38 will fit the disco and provide an upgrade.
I have seen quite a few second hand Bosch 150a units on e-bay US, one new one went for US$50. I bought it!
