Would these oversized one fit the standard MAF also at the other end?

Yeah, you specify MAF size when ordering IIRC.

Yes they will fit std MAF.

 

The oversize area of the TIP is from Turbo upwards to just before the MAF entry.  

 

if you look at this add and select pic number 2 you can see std size and oversize (think someone has already explained this up higher in thread).

The Std is very thin from turbo up and then get to full MAF size only at the very end. The oversize TIP get to the MAF size almost straight away.

 

Our MAF are 2.5" and LCR/Audi S3/TT are 3" so as long as you request one for something like:

 

A Hose for VW MK4 Golf GTI 1.8 20v T / Skoda Octavia VRS etc you will be getting correct one.

Do u need mapping after fitting this with all the extra air flow it will have ? Or ain't it that much difference?

No mapping needed.

The ecu can compensate.
