Been trying to convince myself that a K&N or Apexi induction kit is worthwhile. Does anyone have real dyno results for a stock TT before and after? is it 4bhp or 20?

I gave my K&N filtercharger panel filters a mild hoovering out and they look nice and clean. The car goes great and I've Apexi rear pipes so it breathes out fine.

Incidently I had a nose into the engine of my my neighbour's new Scooby STI, as you do. Opened up the airfilter housing to find a paper element about the size of only one of the stock Z ones. Yet the Scooby STI does 265bhp. Methinks the Z has double the breathing area as is for 280 so unless the engine was chipped or otherwise invested to breath in more in there is prolly not much to gain by going for an induction kit.

True or false?

from JWT's website about my popcharger filter:

 

POP-Charger air filters are designed for maximum air flow by using a 6" diameter venturi surrounded by an oiled gauze filter element. The filter element is reusable after cleaning and reapplying filter oil. Horsepower increases from 4 HP on non-turbos to 18 HP on the 300ZXTT are typical. Available for most late-model Nissans

 

so up to 18bhp they recon, i would imagine this is in combination with other mods.
