I've put it in myself and there are def some changes. More air flow, freer revving. Shifts are smoother because of easier revving I believe. Not much, maybe placebo (and I know some ppl say there's no difference) but that's just my opnion after putting in the K&N.

FYI, I would def recommend taking the whole front half off to put in the drop in filter. Slide it to the left. Then when you replace it (sliding it back to the right), focus on the left tooth and the far bottom left corner. That's where most of the difficulty is.

If it's perhaps faster, smoother, reusable (and thus cheaper in the long run), that sounds like a win-win to me.

Is the HKS hybrid filter a one time use thing or can it be serviced ? What's the time/mile interval for service?

This thread reminds me of events that took place in 2005 when the Mazda Miata NC was introduced.

AEM, of Compton CA, manufactured a Cold Air Intake that relocated the air filter in front of the radiator to take advantage of the direct stream of air.
AEM then introduced it to MazdaSpeed in Irvine CA and presented it along with dynamometer sheets showing a gain of 12whp.

Mazda in turn quickly included it in the list of performance parts that the Mazda racers could buy direct from Mazda.

The problem was that racers are a finicky lot and they quickly put cars on dynos where it was found that in reality the gains were zero.

This didn't sit well in the Irvine executive suites who promptly dispatched Mazda powertrain engineers in the field in search of the actual facts.

Long story short, MazdaSpeed deleted the offering and AEM stopped advertising the 12whp claim.

True facts that I can attest to since I was one of the players.
