first off do not put an intake system on the ti......if you are not isolating the filter from the harmful effects of heat wash from the engine compartment and radiator.And as far as I know there are not any engineered systems that do this on the market yet.
www.ecisbmw.com is working on a system now.I spoke with one of the owners.Scott is right on the bulb issue. I had clears but have since switched to smoke indicators on hellrot it matches considerably better.
