Hi everyone, as my friend has now got the 'modding-bug' after buying a 53-plated MK2 MX5 (might be too new for on here, sorry), I have been tasked with finding a cheaper solution to buying a K&N induction kit, which are over £200! (And you lovely bunch, are my first port-of-call, due to wealth of knowledge on RR) A picture of the K&N 'Typhoon' kit: K&NAnyhoo, has anyone tried this on an MX5? He's after red piping, as well (fussy sod!) Many thanks in advance

The first question is why do you want it, noise or some perceived performance increase?

Thanks for the reply, j4m35. Well, my mate's after one to tidy up the engine bay, whilst adding a bit of colour and a bit of noise!

You can buy a cheap induction filter in halfords .

The problem with most of the mx5 kits is they picK up air from above the exhaust which actually reduces performance the best ones I have seem pick up from under the headlamp often via a duct replacing the indicator.

better off just drilling the airbox. It's placement isn't bad really. You won't gain anything, but it'll make a nice noise with an aftermaket panel filter installed. Most of these induction kits afre a bit snake oil! The jackson racing airbox is known to give some gains, but at £300 is mega expensive for what it is and probably any gains in bhp are offset in a drop in torque (the jackson racing setup reduces the length of the inlet tract significantly)

There's not a great deal to it.
100% seriously, a mate reduced intake temps by fitting a cone in a tupperware box wrapped with tinfoil. A well known Subaru tuner made an airbox out of a plastic bucket wrapped in tinfoil containing the cone filter. This was in a car running over 400bhp.
There is a high pressure area under the bonnet of an MX5 in the corner by the scuttle behind the standard airbox position.

Hmmm...'universal' usually means 'universally won't fit'. Have a look around on MX5 Nutz, Miata.net, etc. to see what others have put together in the past.

The K&N kit looks like an unnecessarily long run? A pair or silicone couplers, a 45 degree bit of pipe and a universal or Honda S2000 cone filter should do the job.
I use an old breakfast bar leg cut to size in my Renault with a mushroom filter.

I have a K&N Typhoon kit fitted to my car (bought it second-hand,thankfully!). While it is true that a lot of aftermarket kits sit the filter a little close to the exhaust manifold you can reduce intake temps but fitting some heat shielding or shrouding. In lots of more heavily modified cars they use a holesaw and cut into the passenger side scuttle and place a filter near there - you can get quite a nice draw of cold air there (even running near the exhaust). Tbh if it's just noise then drill the box. If he wants to clean it up a little cheaply then get two silicone joins, a straight stainless pipe section and some jubilee clips... FYI, the K&N kit makes no perceivable performance increase, just a lot of noise under load haha EDIT: Yes, a lot of people fit a short pipe and bend and stick the filter down the driver side, but imo it's messy, the bed is usually sharp and if you look down the passenger side there is actually holes in the crash structure to allow air into that section of the engine bay anyway...
