did I say ram? my mistake, I meant cold air induction system, like this one (avail. for the Speedster in 2/3 months)

even a simple panel KN replacement will do good anyway....the car has a pretty straightforward airbox, no curves or kinks.
reliability? 2 years warranty, plus one of the most advanced engine around, no maintenance ever required, other than fluids, filters and plugs!
348 had horrible gearshift and lousy steering feel, on top of a tricky stability...and talk about reliability!!! owner's nightmare! of course it is faster, but not even close to the fun you get into a speedy/elise...you just gotta try it to understand.....
cheers!
