yes, it's the maf from the Summit WAGON/Minivan. It just looked like it'll flow much better than the stock mas that the galants came in. I've got a 2g mas, but when i've got the 2g mas hooked up, the car doesnt idle as well(will obviously need a tune) but with the Summit Wagon/Van maf, it idles very nicely and I can feel a faster spool and much better response. Only shitty thing about this is that I don't have a wideband o2.
I've got the Summit maf in and it drives much better than the stock intake. spools faster and looks a little better. With the 2g mas, it fits with some customizing, but there is no room for the air filter. I was thinking about getting a Evo mas, but i havent seen one around locally yet. The Summit MAF seems to be working quite well actually for DD, I have not pushed the car to see it's limits yet because the car feels great as a DD right now, but I'll post some pics or videos of it if needed.
EDIT: I know it may not be as well as the 2g mas, but it seems to be driving and idling perfectly
