Is K&N typhoon worth the money??
Discussion
I thought it was brilliant when I has an MX5. You didn't notice it when driving normally but if you accelerated hard or were at higher RPMs then it made the car seem like a proper sports car.
I paid £90 for mine and sold it for the same when I sold the car. If you can pick one up used on eBay then I would recommend it.
The mk2 1.8 kit fits all mk2/mk2.5 mx5s and can be adapted to fit mk1s

The general review is that they don't do much (anything) for performance, but make the car sound much better. I had one on my previous 10th Anniversary, but not got it on the current car. Have been wondering about it, but not sure it's worth it for a little extra noise. There was a gap between owning them, plus different exhaust systems so not sure how much different there is with it.

But they also say that it supplies colder, denser air. Unless a heat-shield is fitted along with some ducting supplying cold air from in front of the car it will actually be supplying hotter air.Still, it does sound good. Not £250 worth of sounding good but probably worth it if you can get one 2nd hand.

Would you not lose performance if it's sucking all the hot air in from the engine bay?
Yes, they need a heat shield with a cold air supply to make them effective, otherwise they are sucking in warm air as you say. It's why I laugh at anyone that says they've fitted one and now it's so more powerful. Breathing "easier" isn't necessarily what it needs. Have you ever taken a good look at the stock crossover pipe? It's not just a plastic pipe, it has a resonating chamber half way along that will pulse with the airflow and work with the engine. Also, the snorkel after the airbox isn't that shape and length by accident. Mazda will have done a lot of testing to get it the perfect length, shape and diameter to work efficiently with the engine to give the best balance of performance, economy and emission control and it also moves the air-intake to a colder area under the bonnet. The ecu will have been tuned to work with that setup and doesn't "learn" like in more modern cars to adapt to the new airflow.
Is it really a big surprise that if you take all that away and replace it with a straight tube and a big filter near the exhaust manifold you will be compromising the setup? Especially without any ecu retuning.

I looked at the K&N Typhoons but decided not to. It's a fair amount of cash (inc declaring to the insurance company) for no massive benefit in my opinion. Don't take what I say as gospel though - That's the opinion from my own examination/research.
Speaking as someone who once worked as a design engineer, I'm with Lazza. Every bit of detail in the car has a reason for it's properties. If the intake is a certain length and shape it's that way for a very good reason. (Hint: Cars are designed to the nearest penny, there are no 'pointless' features)
I've decided to save for some heated MK3 seats instead, they are so, so nice.
Kind regards,
Matt

Fitting them is a bit of a PITA though. Drivers side isn't too bad but passenger side is too wide to fit properly. That's a subject for a different thread though...

I ordered my Typhoon kit from teh states via Amazon and it was cheaper than that, $200 I think? That's delivered to Australia!
I feel no discernable speed difference but by Gods it sounds good! Looks cool too! I got a heat shield and sprayed it the colour of the body as well. I could not give a monkeys if its 1hp down on standard.
