Tegiwa intake comparison/test

[Jester04]

I'm not afraid to spend coin on something I want. However almost 2k for some turbo noise is a little bit crazy.

Honestly for power per dollar the PRL is hard to beat, looks pretty good too. The Carbon ones are way better in the cosmetic department.

Curious to hear more about your perspective because I'm not following. Which of these intakes are "almost 2k"? I don't see this as net neutral from a power perspective. The testing methods aren't exactly clean, but a majority of these intake systems are indeed making power. Power per dollar may not be as eye popping as we'd like but the power is there. They're making power over the stock airbox on Tegiwa's dyno and some manufacturer's have also stated claims. You will undoubtedly feel 20 lb-ft of torque in the midrange on the street in a 3,200 lb sedan.

Would definitely be interesting to see this same comparison but on a car that has more mods like a bigger DP, turbo, etc.

I'd love to hear one of the enclosed ones in person and see how they compare to the open style.

Eventuri , group m and I believe prl carbon are around 1500 from what I have seen.

Some Dudes that paid $5k-$10k markups for their cars that got nothing complaining about a $1500 carbon intake is crazy ?

Since price matters I would've loved to see the PRL HVI with the Turbo Charger Inlet.

Thanks for posting this. While these tests or shootouts are never perfectly scientific they're still enjoyable to watch and are good enough. It seems the PRL is the best performing intake relative to price. Armaspeed, Infinity Design, Eventuri, and GruppeM appear to have seperated themselves from the others not only in performance but fit, finish, and overall quality. Of course all that goodness comes at a high cost.

I'm keen to know if the gains over the stock air box are nullified once the vehicle is tuned. In other words, if you were to tune the same car with the stock air box and then tuned the car with the GruppeM intake for example, would the results more or less be the same? Will an aftermarket intake allow you to tune for more power over the stock air box? If the answer is 'no', once tuned is an aftermarket intake largely a sound and lower IAT play? @Vito.FL5 @Jester04 Thoughts?

I have tuned a car with the Gruppe M intake and didn´t like how it affected maf readings. Fuel trim went to -10% in high loads as soon as the intake was installed. This means the maf is reading more air that it should, so car will run richer, with less boost and less timing. It can be fixed with tuning but I didn´t like it.

(I´m not trying to hurt gruppe M here, maybe there is another factor that I´m not taking into consideration, and since it´s a remote tune, I have little control over that, but it´s on my radar now and I will keep a close eye to other cars with the same setup to understand what is going on)

The car was 20.000km from me so I don´t know if anything wrong was done on install but I found the results to be very weird.

Many intake brands design the air box and maf housing to read slighly different than stock, so ecu compensates with more timing, less fuel and sometimes more boost, depending on how the car is tuned at the factory. But in this case the difference in readings were contrary to what could give better results.

So, there is no simple answer to your question, the intake can make power by simply being less restrictive and allowing more airflow to the turbo, or by tampering with the maf readings. If it´s less restrictive then you will make more power even when tuned, if it just tampers with the maf readings then after tuned the power difference can disappear.

I am using most of my time into working on a tuning platform for Porsche, so the Honda is moving slowly, but I will make some tests soon without the MAF sensor, tuning only by Speed density, if it goes well then I can move to a headlight intake lol

I'm not sure you'd see a measurable difference with the upgraded inlet pipe on a car that is close to stock but they certainly look nice!

It could be a measurable peak difference, plus or minus or as you hinting, nothing at all. I don't have that information obviously but I am curious. I simply used pricing as the doorway into the discussion. It makes sense to me given the lengths they have already gone through. The more information the better... I am biased however.

The more testing the better! We love the data.

I did not watch the hour long video. Anyone care to recap and summarize best to worst intake performance?

For what it’s worth, following IMW’s Facebook and comparing two FL5s with almost identical mods but one had an intake and one had a drop in filter, surprisingly the drop in filter car put out more power. Obviously variables exist- different cars, ambient temps, etc., but the intake appeared to be the only different mod. Just wanted to share to mix up the discussion here.

With intake was 378/396 :


With drop in filter was 386/410 :

Something to keep in mind is that any sort of testing focused on the intake should be completed with the hood closed. This is not the case during your typical dyno session. Even a short ram doesn't look terrible when tested with an open hood.

lmfao……. They threw away ADM so easy but 15/20 hp/tq at 1500 is expensive

I'm interested in seeing Eventuri inlet pipe paired with the PRL HVI. That is appealing to me. CF should be better at managing the heat than a metal inlet pipe....hmmm
