GR86 MST Intake - Potential Group Buy (w/ generous discounts)

[S18RSG]

Hi all.

A friend and fellow GR86 owner messaged me this morning about intake options for the 86, and my preference has always swayed towards the MST. Overall design, quality and logical efficiency of the intake make it about the only one I'd recommend.

He asked me about potentially getting some discount from them (apparently I've built a bit of a reputation for this kinda stuff with the Supra guys), so I've been in touch.

They're both willing and seemingly excited to offer a group buy of sorts, for those interested. No real timescale, but obviously the sooner the better for those of us lacking in patience.

The intake is available from MST direct here: https://mst-performance.co.uk/mst-performance-intake-system-for-2021-toyota-gr86-subaru-brz-2-4l/

Retail price is £355.

MST are willing to discount this price by 10% to £319.50 for the inital group.
However, if we're able to secure a reasonable number of people, this discount can be raised to 20% meaning a potential price of £284.
So far, they're talking about needing around 20 orders to secure the 20% discount. Perhaps unrealistic, but I can renegotiate these terms should we get a decent number of people interested.

So, who's in?

If we can get 20 people, for 20% off. I'm in

I might even be in at 10% to be fair (lets see how many are interested first, but if we get 19... I'm your 20 - 100%.

Good review of it here tbh...

Cheers mate. Will count you in for now. Obviously before we place any orders I'll ask everyone to confirm their place.

Want to intake eventually but want to get some miles on first, plus I don't want to take the p1ss with warranty too much. Was going to get a panel filter for now. How are these for throwing an EML? I've heard some intakes do trigger it if the car is fussy.

Intake is never gonna affect a warranty mate, especially not if you do what most of us do and get all the work done at RRG.

There was one known EML thrown with this intake, and it was proven to be because the owner installed it incorrectly. Instead of mounting the MAF at the vertical, they mounted it at an angle and the car didn't like it. Once corrected, it was fine.

Will have a think about it, because I like the idea of better induction sound - anything to make this engine platform sound better to be honest! But I too am a little wary about warranty implications. Very easy to say it's never going to be an issue; but you are potentially changing the filtration level the air intake, and I'm pretty sure it might also affect the air/fuel ratio. Whilst we all know that in practice, that probably won't do any harm whatsoever, it might be enough for Toyota to wriggle out of engine claims in the future. And whilst getting it done at RRG is great if you can, I live at the other end of the country, so a 450 mile round trip to install an air intake isn't practical for me. If I change it, I would have to rely on being able to revert back to stock in the event of a problem, which hopefully isn't too difficult.

Good review of it here tbh...

I watched this and it does sound pretty good....but he's since done two other videos following up because he ended up with a check engine light, and then he removed it entirely because he said it was driving weird. @S18RSG - is that the same guy you mentioned? His videos are a little light on detail, but there was no mention of fixing the issue by ensuring the MAF was install correctly (and it was installed vertically in his original install vid) - only that he reverted to stock and the issue went away. Video below - the first 3 minutes talk about taking it off, the rest is just irrelevant vlogger guff from what I can tell.

(

I'll hold off committing to anything for now, but definitely keeping an eye on this

I can't say for sure, but I know the guy who was complaining about it on the US Facebook page had linked some videos he'd made, so I'd say there's a fair chance.

It's testing my memory, as it was a few months ago that I saw it, but I seem to recall someone pointed it out to him in his pictures/videos, and then tried it on his own car and had the same issue. When he then mounted it correctly, the issue went away.

In theory, there's no real reason a CEL would be caused by the intake, unless it was getting too little air or the MAF wasn't reading correctly. Can't think of any other reasons for a CEL relating to an intake.

 

[Conscript]

Probably not, then as this guy's install was done a only a month ago. Still, you're right, it's usually something to do with the MAF. I'm just a bit wary about fiddling with the intake; I remember with the GT86, lots of aftermarket options actually reduced power, which hinted that the OEM one was probably quite finely tuned. But I do admit that induction noise is quite addictive

 

[S18RSG]

It appears to me that a lot of the power increase just comes purely from removing the carbon filter, depending on your source, that seems to net anywhere from 4-9hp over stock.

This intake is all about the noise really. No intake on any car is ever gonna give you noticable power gains, no matter how good their marketing is, and that's why I would personally never spend more than a couple hundred pounds on an intake.

 

[Conscript]

Yeah I've always been skeptical about power gains from intakes. But that's fine, not everything has to be an objective improvement. Perfectly justifiable to just want to improve the sound.

How easy is it to get replacement filter elements? Do we know how much they cost? I can't seem to find anything on their website.

 

[KobayashiMaru86]

It's probably a standard cone filter. Last car had a carbon box with one of these in and you found the diameter and bought from demontweeks or eBay. Being open will help keep an eye on it for cleaning and oiling.

 

[Swizzle]

Currently £289 on ebay, prices are coming down nicely with popularity

You have to open two clips, pull the original out, put the new in, close the clips.

I was referring to the MST intake

Your car should not have that filter.
Its US only.

And yes, the stock intake is the best. There are tons of videos with dynos.
Everything else is only for noise and reduces power!

Also the check engine light may come on, when you remove/modify the stock airbox.

The whole intake system, whit its resonators, lengths and diameters, is fine tuned piece of art.
E.g. the length of the intake manifolds is made for (super)charging the opposite cylinder.
E.g. the snorkel is made to generate underpressure to speed up the sucked in air
E.g. the big resonator removes back bouncing waves of air, that would slow down the incomming air

The one and only modification, that makes sense, is using a aftermarked drop-in filter.
Everything else will result in loss of power, no matter what the "tuners" promise.

Hello,

It may be a bit late but - wondering if we are still doing a group buy or it has already be done? I got a frd who is interested in this so helping him to ask.

Thanks.
