K&N Cold Air Intake system

[NocturnalEmber]

This is 100% why I went with the Nismo design. It was between that and the Boosted 6 setup. I LOVE the sound of it but I couldn't get past the heatsoak.

Time has proven time and time again that sealed designs work better. Dyno tests with an open hood and 4 industrial fans pointed at the engine bay don't mirror real world results.

I'm running the Nismo intakes myself. Yeah I wish they had more induction noise but its better than the factory airbox, and an open filter design was a no for me.

The secondary elephant in the room is the air to water system being pretty inefficient; thermal runaway is a question of when as opposed to if. Greddy's air to air kit is on my list eventually if I decide to address it.

If you want intake sounds, can't you just run the box unopened? Not that I would but I assume that's an option for the Nismo and the AMS setup. Any tips on install? Sounds like a pain but AMS has a solid set of instructions.

Curious why you went with the Nismo intakes and not the AMS? AMS makes them for NISMO, and the AMS comes with the clear window, which I think gives a cool look.

Literally just price and the NISMO brand. $499 w/ free shipping was a solid deal for the NISMO. I ordered it direct from a Nissan dealer and it shipped within 12 hours.

With that said, I do think the style of the AMS setup is awesome.

I bought my AMS intakes from CZP, an they have the best price I have seen. Lower than the NISMO, which I was looking at, but really prefered the AMS look better. AMS Performance AMS Red Alpha Cold Air Intake System - Nissan Z 2023+ RZ34 AMS.47.08.0002-1 400z - Concept Z Performance

The hood sits on top of the k and n which makes it sealed. Nice design and can hear the sounds a lot. Only flaw is the installation with the clamps for the filters

open air filters, like the new 3.25" AMS intakes (not on their website yet), are fine for things like drag racing where it's massive volume of air for intense short periods of time where heatsoak doesn't really play into it. street, track, etc. pretty different story. The 3.25" intakes were used by Sonic and AMS in their recent competing world records... I think AMS hit 1/4 mile in 9.27 secs stock engine, transmission

This is a crazy good deal. I'm still happy with the Nismo branded setup but if someone wants AMS, this is the cheapest I've seen it by $40-$50.

Good point, I forgot the K&N had that setup. If it was still on sale at $399, I would consider it but not at full price. Most places are out of stock anyway. I dislike that they continue to use wet filters too.

Don't mean to be a dick - but again you are all over thinking heat soak with a turbo the exhaust that's spinning compresor is how hot - running open intakes doesn't changes your charge temps. If you want to argue when tracking the car and in your 20th lap your charge temps went up and you're blamming that on open intakes - head explode. Go A2A or upgrade your intercoolers. If you put anything less than a 3" intake on these cars you get ZERO performance benefit and then run them close and you're not even getting the cool noise benefit. if you DO NOT use yor car primarily for road course run them open.

Wish I would've listened to you when you bought yours instead of the K&N. Yeah, the K&N looks nice, but I mainly wanted the turbo sound. I got a hell of a deal on the K&N though.

Or run a vented hood and open air intakes on road courses problem solved everyone happy

As it's been said many times, you're charge air temps will rise, without it closed or heat shielded. Your water temperatures will rise with it (quicker with it open), and it'll be harder for the hot water to drop temperatures (even if you've upgraded your Intercoolers & heat exchanger). And with hotter water in your Intercoolers, your engine is pretty much getting hot air.

Solution, if you want open air pods, run them in the very front and low. OR as mentioned, run a hood with heat vents

OR OR OR!!!

Drive with your air conditioner on full blast cold
