1.5T Big problem with MAF sensor when installing K&N typhoon AF

[SuperTony]

I finally did it!
Today I have sucessfully install the K&N Air Filter system with the stock maf sensor. I drove for about 1 hour, 40km, no code, no funny things at all.
I ask a local workshop to make a metal adapter (ring shape). Then the stock MAF sensor can go right on just like stock. But since its a little but smaller than the SI MAF sensor, the bolt will not fit. I have to use AB Resin (mix A and B together) to glue it temporary and it turned out so well. To be on the safe side, I also use Silicon sealant to seal every single gap.
The only problem is that the stock MAF plug will not go all the way in, because the shape of K&N hose will prevent it went in further. So I have to use a zip tie, but nothing so bad.

I've done it before with the OEM airbox and that worked perfectly.The si maf sensor hole is 32mm and the non si is 26.3mm.Just need a reducer and the mounting holes are also different.The most important thing to do is make sure the maf sensor sits at the same height and Angle towards the incoming air.

With the OEM si airbox retrofitted into a non si and using the non si maf sensor my LTFT where at 0% VS stock at -7%.

An aftermarket intake could be much different.The si maf housing is bigger then non si .So better check your fuel trims.

Mine was a Typhoon K&N Short Ram Air Filter. My car used to run ~8.5liter/100km. Now its only ~7.2/100km in city and ~6.2/100km for highway, which quite surprise and amazing.
For the noise: I used to own an Elantra Sport with Short Ram Intake and it’s pretty noisy all the rev range. But with the Civic, I can only hear the roaring at 3000rpm or higher, below 3000rpm, its completely silent like stock airbox.
For the performance: definitely much smoother when accelerate, and I can feel the engine produce quite a lot of power without reving in high rpm like the stock.
But in low speed and city, I can feel a little hesitate, not too much to be annoyed at.
