Volant Intake System for TFSI

<< < (47/47)

Yeah I remember reading some time ago the Neuspeed intake was one of the better ones for fuel trims, but none of them are anywhere near close to the OEM error margin unfortunately.

It's not helped by the terrible MAF location VW chose to use. It's too close to the turbo, so heat, PCV oil (K04 even more so) and turbo flow reversion work their way back up the TIP and onto the MAF.  It works OK in the stock intake with the laminar flow grid and standard power, but start turning things up and the MAF doesn't like it.

That's why on the EA888 engine, the MAF was moved much further away from the turbo.  You can get away with a lot more on those engines in terms of aftermarket intakes.

The Revo intake was terrible. I could only stomach it for 2 weeks and then sold it.  Good to hear GIAC/Evoms paid attention to the MAF as most others don't. It's not like it's the engine's primary load measurement or anything  :grin:

Another good intake from my researching is this one, but look at the price of it  :grin:  It still won't be +/- 1% error like stock though. Nothing is.

I've tried the HG motorsport intake for the 1.4 TSI CAXA and boi do I regret it.

I was dumb enough to pay a little over a hundred euros for a shiny pipe and a filter that wouldn't even fit in my engine bay. Had to wait around 3 months and send constant emails while they kept making excuses why they cant ship. Funny that right as I asked to be refunded, they were able to ship it the next day..

I had to really stretch the fit when trying to bolt the pipe onto the screw hole next to the battery. And guess what? after like the 2nd rev, the metal extension that was welded onto said pipe, broke clean off. The rubber adapter-hose that was supposed to connect the pipe to the plastic intake inlet on the turbo was also the wrong size. It was a very loose fit. I had to wrap said inlet with tape so i could tighten the pipe enough for it not to fall off. Oh and did I mention I had to cut a solid 10cm off the pipe, just so I can fit the filter into my engine bay? crazy...



Here's the intake in question https://hg-motorsport.de/en/air-intake-pipe-vag-1.4-t-f-si-122/125hp-e.g.-golf-mk5/6-audi-a3-8p

Safe to say I wont be ordering any of their overpriced stuff any time soon.

Speaking of "terrible MAF location" ...even Neuspeed made a change; moving the MAF further upstream of the down-bend.

Took me some time but I did eventually find a pic of the older MAF position on a Neuspeed P-flo, before the revision;
