ITG Maxogen Air Intake vs. HP Cold Air Intake

[RandomX]

Hi All,

Is someone able to explain the difference between these two air intake system for the 6R Polo GTI?

1. ITG Maxogen Air Filter Intake System For VW Polo GTI 1.4 TSI

2. APR - High Performance Development for Audi, VW and Porsche Vehicles.

Price for the ITG system works out to be ~$441 excl. shipping

Price for the APR/HP system is $795 (providing you can pick it up from one of their dealers)

I can find graphs on the performance gains by the HP CAI, but does anyone know how the ITG system performs?

Any feedback on whether the HP CAI is worth the extra $$$?

Cheers,

Josh

All I can tell you is what someone over here achieved with his GTI + Milltek and ITG: 233,4 hp on the dyno

Simple answer? No. If you are happy to pay $300 for a speculated difference compared to the ITG (if there even is a difference) AFTER tuning.....

Hurdy over in the uk is running the ITG intake and saw a power increase prior his stage 2 tune, I "think" it was 9whp so what's that, around 3.6wkw? Stock I would highly doubt you would get any noticeable difference, other than intake sound.

I don't want to sound like an APR basher here because enough of that occurs in other sections o the forum but "10-15 wheel kw increase" sounds like that would certainly be on a tuned car, most likely running stage 2 (Guy woul have to confirm) but the line that says "hot air feed eliminated" is just plain wrong. The polo GTI stock intake trumpet is already a cold air feed as it sucks air from the upper front grill and I regularly see intake temps maybe 1-2 degrees warmer than ambient unless I'm sitting in traffic when the heat soak starts building up in the engine bay.

Does the oem intake have a ventilated base?

I know that the 2.0TSI intakes have an open base so while they can suck in cold air from the front, they also suck in hot air from the engine bay.

i believe the stock intake has a small opening at the bottom... however it only looks like it's there as a water run off...

cheers gavs for the input regarding the intakes

Gav's, all our figures are for a tuned car, no one with a stock ECU has bought an airbox off us.

Oh, your polo does have a hot air feed, that is 50% of the air going into your airbox is fed from behind the radiator (the hot air feed), generally used by OEM's in sub zero climates I'm led to believe. If you dismantle yours, you will see it.

The ITG does a very similar thing to ours (eliminates the hot air feed).

One way to test is to do what we did - back to back a series of tests on the dyno between the two intakes - we obviously only did ours vs stock, on two separate test cars.

[Guy_H]

Oh, P.S. The test car in question had an intercooler, no exhaust, average increase over 6 runs (not the maximum or minimum gains, the average), so not a stage 2 (I would call stage 2 with a full exhaust).

[gavs]

Thanks for that info Guy. Not trying to sound like a knob, but was the car running the stage 1 tune, or something more powerful? I ask because most people don't consider hardware (myself included) as a stage 2 tune, they would asses that as a stage 2 package.

Still disagree on the intake though

[readerr0r]

The graph key pretty much sums it up fine imho. It says the HP gains were measured on a Polo GTI with the APR Stage 1 ECU tune and HP Intercooler.

I think it's fairly safe to say that the car would need to be tuned to make the most out of the Intake

Guy, how many KW's at the wheels does that polo gti make with no mods whatsoever?
