Smaller engined cars can actually loose power when an induction kit instead of an sports airfilter is fitted.
It can be challending to deliver COLD air to the engine as the temperature rises under the bonnet . . .
. . . so to summarize, if you have a large engined car, fit an induction kit with an cold air feed. If you have a small engined car or one with little power in the low rec band, fit a direct replacemtn sport panel air filter
