The ITG is far too expensive for what it is… a cone filter in a black flowerpot!

42

I agree. It surely can’t be worth �90 more than Pipercross.

43

to be honest they both sound like an awful lot of money for what they are…just where is the value in either of the kits.

44

on my old s2, i just put a 4" cold air feed pipe into the original air box, put a decent panel filter in, sport exhaust and decat’d it which got rid of any drone and gave it a nice sharp sound. This is the way im thinking of going with my exige, dont get me wrong some of the cf stuff looks really good but i just struggle to justify it personally.

Brendan,
I was in the same position as you, wanting to hear a bit of induction roar and then faced the difficult choice as to which induction system to fit.
What you must appreciate is that the nearside air intake is relatively low compared to an S1 and alot of road debris is thrown up by the front wheel.
Drawing engine intake air in at this location will blind off a filter very quickly and regular cleaning will be required.
Consequently air needs to be drawn in at a higher location unless you are prepared to devote time to regular filter cleaning.
Another consideration is the free surface area of the filter element in terms of reduced pressure drop and also the ability to hold a decent amount of foreign matter before cleaning is required.
The difference in air intake temperature at the air scoop or slightly higher up in the engine compartment is minimal.

So after careful consideration I chose the ITG system. I know it is more expensive but the filter has a large free surface area, its a foam type filter so can trap a higher amount of particulates, the air intake position is correct, quality of manufacture is excellent and the resulting throaty induction roar is totally addictive.

Regards,

David.

PS. I dare say Mr Pesky will object to all this additional noise!!!

Well, it seems that these kits may well do what I want from them, but they are simply too expensive for what they are. Why do we need any carbon fibre stuff in the induction kit? Is it simply to justify the inflated pricing?

I’m going to hold off for a while. Maybe somebody will offer a sensible alternative.

Hey, Brendan, you used to like “shiny bits”

49

Not much point in having shiny bits hidden away in the side of the engine bay

50

its a bit cheaper if you buy from B&C

51

I would gladly buy a non-carbon one, is there any about?

He’d better get used to it then coz I pass Residence Pesky every time I go out.

Didn’t I tell you that Father Christmas brought me one of them spider thingies?

I thought you were joking:

although it looks more like a watering can to me

I’ve not got a clue if these are suitable for the Yota engine, but they work a treat on Hondas

Interesting pedigree but this sounds a load of bollocks:

"CDA filtering system, now available in the second step EVO 2, is connected to an air intake in the front of the car through a black alloy ducting. Thanks to the dynamic air intake you have a true supercharging system that conveys cold air at a speed and capacity much bigger than with traditional systems. The airflow entering through the dynamic intake is still further accelerated due to the conical flow variator inside the carbon dynamic air box. Finally, dynamic overboosting, greater airflow, higher pressure and colder air are the elements assuring a considerable increase in engine performance in power and torque. Thus demonstrated by several tests on a Dyno. CDA EVO2 WING, available in 2 dimensions, can be fitted on every kind of car. "

However, I didn’t fit it to my car for performance gain purposes - needed a filter, & those traditionally (at the time) fitted to Honda conversions, were “Hurricane cone” types, which were problematical at trackdays due to the massive induction noise! The BMC works a treat, & draws cold air in at its location adjacent to the side inlet (again, unlike the alternatives). It also looks good (IMO), is light, & costs around �150. If it gives any “extra” horses over & above the standard Honda filter, then that’s a bonus

Interersting in that the aftermarket kit is worse than the standard below 2.6k revs - why would that be? Is the filter letting too much air through?
