Look at the intake that the car comes with. It's a great design. If you go aftermarket, most I've seen are hot air intakes. So if you want an intake, realize most are bad for performance, so do it for the bling factor. You will gain 0 performance

Nu uh. I put an intake on my Prius and it had at least 100 more horse power at the wheels.

I really hope your joking! No air intake will add 100hp from stock just doing the intake. The problem with open air intakes is there is no heat shield. And your pulling in hot air from the engine bay. SXTH has intake that comes with a optional heat shield, and then utilize the stock air tube that feeds the stock enclosed box to get cooler air to the open air intake. Combine that with a snorkel with that heat shield, and you should see lower IAT's. The engine bay while moving actually doesn't get that hot. Air movement is actually really good. Not sure if anyone has checked the heat of the enclosed sealed airbox right after a long run, its not hot at all. What is hot is the Air Intake Tube. IMO that needs to shielded from heat and nobody is doing that right now.I haven't seen one Intake Tube that comes shielded from heat. I'm going to stick with stock with a Pipercross Air Filter, and then a snorkel to pull air from the grill.

Well the Prius is different. That's a beast. It needs the extra air!

I've never seen a heat shield that isolates the hot air completely. A box fed from a cold air source does just that. I've seen claims about a metal tube not heat soaking like OEM silicone air tubing. I haven't tested it.

This is simply false information. The Forge & Pipercross CAI's will show a 10+ hp whp increase. With the Forge Veloster N Turbo Inlet Adaptor added, nearly another 10 whp. Data Logging shows a very small increase in IAT's at idle. At normal speeds and above, ambient temps with IAT's.

Show us where there will be "0" increase. Mind you, I've already dynoed with both, so you need to come up with some factual information to support what you've stated.

Heat shields don't really work, unless they're enclosed against the hood and properly positioned in the inlet air flow. The stock box is far more restrictive than an aftermarket CAI. The pipercross filter won't add any further whp, without taking off the airbox top and this is just like running without the airbox.

The engine has zero airflow when at idle, unless the cooling fan is running. The stock airbox and aftermarket intake pulls ambient air, plus any heat soak from the engine. A stock air box won't flow the same cfm, nor will it cool to ambient temps as quickly as an aftermarket CAI. With the use of heat shielding on the intake tube, you can nullify most of the heat soak from the engine.

You all need to utilize the search engine at the top right of the page. There, you will find a plethora of information already available and discussions already on going about, aftermarket air intakes, heat shielding and such. If your want to learn about what's available and works for the VN, you're going to have to start using the search engine. Let's don't start making false assumptions about something you haven't researched or tested personally.:wink:

For the OP@B3arfruit, use the search engine and you'll find what you're looking for. The 2020 VN is the same as the 2019, so anything produced for the 2019 will fit the 2020.

Plenty of information available. Do a search in the upper right hand corner in the search engine.

In love with the forge intake. (And bpv) makes the sexiest low rpm fluttering sound
Looks great Mike! I just ordered mine as well, can't wait for it to come in the mail. I got the velossa tech big mouth as well, just a little worried about water getting into the intake filter.

With the forge intake you're getting rid of the airbox anyway, so any water that does get onto the filter isn't going to be able to flood it enough to get much into the engine. There's no box under it to fill up.



I had some concern with the VT big mouth and the stock airbox though since the stock airbox has almost no water drain holes inside. Most of them have at least a few 1/4" holes but ours has a single small 1/8" hole and that's it. I was worried about what would happen at the touchless car wash because it really puts out a lot of water and sprays it hard enough to go right up the snorkel. I drilled three 1/4" holes in the bottom of the airbox in 3 different spots so no matter which way the car is sloshing it the water will find a drain hole. I still was worried the first trip through the car wash, but it was fine.

You can't get enough in the Velossa Tech Ram Air Intake or the Forge Unit to hydrolock the engine.

I don’t know how to make a new post on this thread but I purchased and installed the AEM intake for the N and it definitely had noticeable gains and sounds amazing, I have one concern though and that is the amount of turbo flutter, I know it does it with out the top of the air box on w the stock intake but although the flutter sounds amazing I am concerned about the longevity of my turbo due to the flutter and was wondering what I should do about it or if it is ok.

I also think I should add I am using this in conjunction with the velossatech big mouth

What you are calling turbo flutter isn't. It is simply pressure relief from the BOV or Bypass Valve.

Turbo flutter, also known as compressor surge, occurs when there is an abundance of pressurized air in the turbo system. When the engine is not able to combust the full amount of air pressurized by the turbocharger, this excess air will build up in the intercooler system.

The aFe Takeda Intake will work well in conjunction with the Velossa Tech Snorkel. However, don't expect a 10 whp gain or equivalence in torque.
Why wouldn't the AFE closed box intake with Velossa Snorkel gain at least 10 whp/tq, if short-rams like Forge can produce these kinds of gains? The AFE is 4" and has much more flow compared to stock box (outflows it by 39%), so I would expect some gains there. However, you would actually expect this box in combination with the Velossa snorkel to produce more gains than a short-ram system, since you have the additional ram-air effect from the snorkel. At high speeds (gears 3+), you can expect to gain a few ponies just from increased intake pressure coming through the snorkel. I remember that Ford ST test page showing that the snorkel alone made the equivalent of 8 hp gains in 4th gear on the ST. So I would actually expect the combination to produce more power than those short-ram intakes that don't have ram-air... Have you seen evidence that suggests the opposite?
