Almost went for Forge CAI and then I saw this. Forge Twintake with two closed filters sitting higher in the engine bay. The product is still in development but i hope it will be soon out for S3 too. Power gains are awsome too (leon cupra has 18bhp more). Think that CAI is going to wait a little bit.
