I have owned several 240 volvo over the past seven years. I have tried a variety of different manufacturers m.a.f. on these vehicles. This is the first one I have had that my wagon started immediately amd stayed running after pulling the battery to allow the e.c.u. to recalibrate to the new m.a.f. The car is idling well and pulls solid through out the full range. The quality and fit of this part looked good. The burn off wire in the inside of the barrel looks like it's a better design than any I have personally seen so far including the stock units I have had experience with. My 93 240 wagon is running great, no stalling, idling strong. So far so good. Couldn't be happier!
