This product is used with a stock C30 T5 airbox to reduce the intake restriction caused by the ECU cooling fins. Such a spacer combined with a high-flow panel filter is the best way to open up your C30’s lungs. Cone filters and mushroom filters draw hot air from the engine bay, whereas the stock airbox has a ducted snorkel to draw from outside – a cold air intake system.
1x 20mm PETG Spacer
4x Securing bolts
You must use your own silicone sealant to seal the spacer.
## Please note: there is a 10 working day lead time on this part, as we machine these in house ##
