K&N Typhoon Induction Kit 69-9503 ReviewThe K&N Typhoon is one of many Induction kits available on the market for the MK5 GTI. Depending where you look prices seem to range from £200 - £250, I picked mine up as a used item on from a member on here. Unfortunately it didn't come with all the fittings I was expecting but was easy enough to find the parts needed from K&N website together with good installation details.
http://www.knfilters.com/search/product3.aspx?prod=69-9503tfkFitting was straight forward and everything went together well and lined up as expected took me about 1.5hrs. The K&N kit mounts at two positions, one to the engine cover mount closest to the turbo inlet and another to the right side of the engine. Also provided with the kit is a metal heatshield which fits onto the two rubber grommets in front of the battery tray and also to the standard air vent at the front of the grille. Not sure how much heat it actually shields as its not got any foam etc like the ITG kits, but it's a cheaper kit than the ITG. Moreover I think it's designed to funnel air from the standard air vent to the Filter.
After fitting the Kit and firing up the engine I didn't encounter any engine warning lights just the steering light and traction control which is normal if the battery has been disconnected. Tickover was as standard same with noise levels. Upon driving you immediately notice the increased intake noise upon acceleration, I haven't had any whistling noises with this kit on my car but it certainly isn't a subtle kit, its fairly loud. When you take your foot off the accelerator you get almost a dump valve type of noise.
Regarding performance, my car is totally standard apart from this kit and what I have noticed is that the car has lost its low end urgency like it did with standard intake however it seems to have more punch in the midrange and top end. Best description I can give is the car feels it has more turbo lag. Now I'm planning on getting the car mapped after I get a turbo back exhaust so not sure if the map can regain some of that low end urgency that I liked about the standard car.
K&N claim on their dyno chart increase of 18.62bhp@4500rpm & 21.94lbft@4500rpm. However looking at their dyno graph below it shows an increase in torque and power even at below 3000rpm, that's not what I am experiencing with the kit on my car. The car deffo feels less urgent at below 3000rpm than in standard form.

Overall it's a decent kit for the money I paid £115 all in, don't think I would pay £200+ for it but my opinion may change after being mapped but for a standard car I don't think I would bother if I did it again. I miss the low end urgency of the standard intake so I'm debating reverting back to standard or just keeping it on and going for the stage 2 map after getting my exhaust as it may work well with those mods.
Few pics and a short video link, hope you found this review of some use.
