ESS recommends the stock air box but I'm using a Dinan and Ryan is using the BMW performance intake.
I basically lied and told them I was using the stock airbox. IDK if it's because of that or other factors but it's been a PITA tuning my TS2. I've often wondered what it would sound like with that style intake on it.
The silicone hoses will have to go but you can use the throttle body but the throttle body only adds maybe 5 hp if you're lucky
