Re: induction kits
It's expensive, and with a small gain.
The best induction mod for the TS based 156's is to fit a performance air filter to the standard airbox but replace the front inlet with the one from the 156 2.5V6 as the V6 has the resonators in the inlet pipe after the airfilter and the TS has them before. by replacing the TS inlet pipe with the V6 one you get a straight through air system, just like an induction kit.
The V6 inlet pipe is a part you can order from your dealer for about 15-20 quid and the performance filter is somewhere around 30-35 quid, a lot less than the packaged up kits.
Also the 156 engine bay is quite hot and there is not a lot of room for open induction kits which means unless you are going fast enough and can pipe enough cold air into the open kit it will draw warm air from the engine bay - just what you don't want to do...
