I got the K&N replacement airfilter for both my car, Mazda Protege5, and my wife's previous car, VW GTi 1.8T. The difference in turbo charged engine is definately greater, even it's an auto! So, I am assuming it will be a good thing to start the first mod..

I think the impact might be much greater on naturally aspirated engines than Supercharged or Turbocharger engines.
My mother's old 760 Volvo (a Turbo engine) had plugged the filter nearly solid before we ever noticed anything. Even then, changing it did not seem didn't seem to make a huge difference in performance.
In the case of a Turbo engine - I think the Turbo just spins faster. In the case of a super charger - It’s positive displacement - I think it will suck through just about anything.
I would get the K&N anyway - it's more effective at trapping dirt than a paper unit.
I would be careful about the amount of oil used on the K&N on a Turbo or Super Charged engines!!!!
