The typhoon or v2 arent the best for power gains, and you will get heatsoak if sat in traffic, but the heatsoak doesnt render the car un-driveable. They sound amazing, much louder than the aem cai and apparantly the hondata airbox mod doesnt give much noise.
As its a daily I'd be tempted to get a v2 or typhoon for the daily fun factor of the noise, but keep the aem for track where there arent hydrolock worries?
I've just replaced my typhoon with a Tegiwa *runs and hides* for £260 but I need to buy a heatshield. But I'm going for more power with the k100 & supporting mods.
If you want cheap noise without power gains - typhoon or v2
If you want noise with power gains - GruppeM or Tegiwa but you pay a price
Other than there's the aem which you already have (save this one for another thread
lol)
