V1 and V4 seem to be the same length and size from the turbo to the air filter accoridng to the picture. Correct me if wrong
The distance from the turbo to the cold air outlet is the same, but the path followed isn't. The V4 takes a more direct path with fewer bends and transitions. From the cold air outlet, it goes straight into the bottom of the filter box, has to be diverted upward through a flat panel filter, then has to be diverted sideways again to the final duct to the turbo.V1 and V4 seem to be the same length and size from the turbo to the air filter accoridng to the picture.

So, it’s time to upgrade for me, I have the phase one tune with no intake, speed is not my main factor, the noise and flutter is what makes a fun drive. So I think the V2 is best, however I am worried that the hot summer temperatures here in Australia and your comment above about slower speeds (say 0 to 80 mph), the V2 may not be the best solution. Also do you guys redo the tune for me to accomodate the new intake?We prefer the V4 for use with Phase 2 and all of our data is based on that combo. However, as long as you have the required intercooler, the V2 will be fine with Phase 2.
In terms of power, and we have done a lot of testing on this, the V2 and V4 are very close. Under conditions ideal for the V2, it's only about 2hp behind the V4, which isn't enough to really feel. However at higher speeds, like above 80mph, the V4's ram air starts to become a factor. Also at very low speeds, or when spending a lot of time stopped, like in traffic, the V2 heats up more and falls farther behind.
All these intakes have their place, which is why we make all three

If you can afford it, I'd suggest getting the V4. It'll be a "one and done" type of mod. If you put on a higher level of tune, or bigger intercooler, etc., the V4 will be able to handle it all. I myself don't have a V4, but something similar from another vendor, and it works just like advertised. You won't be disappointed!So, it’s time to upgrade for me, I have the phase one tune with no intake, speed is not my main factor, the noise and flutter is what makes a fun drive.

In the stats you have on your website, there is the V1 with a stock filter compared to the V2 and V4. I already have the BMC Airfilter (FB933/01) for the OEM air filter box. I would like to know the difference between V1 with BMC and the V4? Is this info available. I already have an ECU remap and it does 195HP on the dyno already.We prefer the V4 for use with Phase 2 and all of our data is based on that combo.

Hi, are you at similar power as stock with AFE and V1 or same as my car?I'm at similar power with the v1 and an afe panel filter. I would say the £/performance of jumping to v4 would be very small at stage 1. I don't think the intake is much of a restriction at that power.
