3" Maf??????

[Rodreguez69er]

i got a leon cupra (not R) and want to upgrade to a 3" Maf but does the sensor swop straight over from the stock MAF? i no they are different sizes but im just unsure

Yes, the sensor will swap straight over. (But your mapping will be out)

the maf will read low if you increase the size of the maf and dont have your map adjusted to suit.
(as the maf internal dimensions are bigger, more air volume is actually passing the maf at a given speed compared to the old maf).

thats ok gaoona do all mods at once (turbo, injectors, Maf, manifold) then get re map!
