GR86 Best induction kit for airflow?

I wonder how far this is off fitting...

Lovely but toooo much ££££ :(
 
There is version for the GR chaps...

Guy on GR86.org doesn't rate it very highly at all:
"It doesn't really seemed to have made much of a difference in sound and doesn't feel any different power wise... Based on initial impressions, I wouldn't recommend, especially because it is very pricey."

IMO, it does look good in there though -Even better if it was Hydro-dipped in a carbon fibre pattern :)

It's got a GR badge on it so there is 250% GR Tax straight away, can't imagine the 3ft long filter element is easy or cheap to replace over the years either.

"but it's pretty"

The red bit of tube is gopping though.
 
This chap fitted and dyno'd the K&N intake on his BRZ, and you know what, the feedback is actually pretty positive...


I've been thinking about the KN filter more and more recently, listening to sound clips, and happened to watch this same video today. I'm really only interested in a bit of induction noise, an extra 8hp right at the top of the power band probably isn't much use anyway, but it's nice to see that they dyno'd it. More interesting was that they confirmed that it didn't seem to upset any fuelling, or throw a CEL.

Have seen a couple of other clips and it does sound good. I'm not sure why people are often so dismissive of fitting induction kits...sure they don't really have a good cost: performance ratio, but it's no different from fitting an aftermarket exhaust in my opinion, and no one really takes issue with that.

I had a massive one fitted to my 350Z. It did make it sound very tasty. I guess throwing away power by fitting a kit with no little or no regard to keeping intake temps down doesn't go down well with some people. So long as there's a half-decent effort to maintain a cold air feed, the trade off for a cool sound is often worth it for some. i guess it's all subjective.
 
I definitely want some more induction noise but not if I lose power. The intake on the Street Triple has an amazing noise. The K&N adds a very small amount top end but isn't really worth it. It's strange there's not been a consensus on what system is best for these cars yet. It's hard to filter through the marketing crap.
 
It pro

I think its down to some of the legacy shockers that you used to see fitted to cars, as in the £50 chrome Halford specials bolted directly above the exhaust manifold so intakes have a taboo about them, also I don’t think they are flavour of the month anymore as practically everything is turbocharged, intakes for noise aren’t really a thing. I want more induction noise but for me I’m thinking long term, I don’t want ropey filtration performance nor do I want to spend ££££ on replacement filter elements, I don’t believe in cleanable/reusable filters.
 
all this talk has me wondering if anyone has measured standard intake temps in southern america vs northern europe, or does ambient temp have little difference?

We have been measuring intake temps and testing them on the dyno.
Massive difference.

On the dyno with an open cone system we lost a massive 25hp and torque through out the rpm range.

You can feel it significantly on the road and as the fans come on for the radiator power just falls.

We then tested on road intake temps with our intake.

Without a snorkel our temps rose to over + 15 deg C above ambient and you can really feel it too.
More sluggish throttle response.

With the snorkel we are seeing ambient temps.

Intake temps don’t just have an affect because of the physical temperature of the air but the ECU will back off ignition timing when it sees higher temps so a double effect.

In intake systems everything is about intake temps
 
The HKS kit seems to be the same type of arrangement as the TRD but only a third of the price . Would have thought is has few downsides over the stock. Although I am sure this is all marginal gains at best . I wouldn’t as it would have to be declare on the insurance and might lead to warranty issues.
On an out of warranty car I would give it a go
 
We’d like to invite people to come drive with our intake system.
After extensive back to back driving (which means many many bumper removal sessions!)
The difference is night and day in throttle response, low end torque and 5000rpm + power

It is very very noticeable

Best £50 (or so) you can spend on the car.

I'm talking about the full induction kit, not just a drop in filter. I already have the HKS panel filter and although only 40 quid or so I wouldn't bother again.

Unless of course you know somewhere selling the full KN intake kit for £50, in which case sign me up :D
 
They may not the the oiled filter elements cause MAFissues eventually. (I actaully have K&Ns on my other three,... but would prefer a dry option on a new car)
Is there any evidence of this? I did a bit of reading and it seems like this idea that oiled filters foul MAF sensors might be a bit of a myth, and K&N have even directly addressed the issue: https://www.knfilters.co.uk/maf/massair.htm
