Hello here,
sorry to dig this topic, but some advice would be awesome !
I plan to do some upgrade on a 116i .
I'm plan to do :
- K&N filter
- Spark plugs
- Intercooler
- Complete exhaust catback
- GFB DV+
- ?
But in regards of your experience, I would like to have your ideas.
- Which intercooler would be better , 135i OEM or aftermarket model (bigger) something like this :

- I've read that you've got really big problems with sparks plugs, what would be recommended ? 135i oem ?
- In term of perfs, do a down cat is really recommended? what about the
Sound comfort?
- Do an oil exchanger need to be mounted ?
Thanks fir your advice's guy's !
