Did you opt to not get the intake duct as well?

 

Not available yet but on its way. Will install as soon as I have it.

 

Is this for the GRY or specific to the GRC?

 

Their website says both. I hadn’t heard anything about this haha but I am familiar with forge as a company for some evo parts

 

There is a difference between the Yaris and Corolla where the intake tube from the airbox attaches to the radiator support area so the idea is to check what needs to be modified.

 

It’s interesting because they advertise it as gr Corolla compatible already. However based on the images it doesn’t seem to match up to the factory location at all but then again it’s the Yaris and they only have one image that sort of shows it

 

Any videos of the sound??

 

Wish it wasn't carbon. Or had a non-carbon version. I can’t think of a more useless and needless material for an airbox that will stay unseen 99.99999999% of the time. Plastic or other composite materials will yield identical performance results without the cost of carbon. In addition, carbon resin exposed to constant high heat engine bay temps tend to degrade quickly.

I like Forge stuff. I have Forge stuff on my Veloster N. Like their intercooler and associated piping. But this is clearly just bling for the sake of bling.

Ran carbon DINAN parts on my old m cars for years with no degradation to clear or otherwise. It depends on the quality of the clear that’s used.

 

The issue with plastic is that it needs to be injection moulded and creating molds are extremely expensive. So for somewhat limited production carbon works out to be cheaper. Fiberglass is a cheaper option but not as attractive as carbon.

 

Or rotomold

 

hows the inlet duct look/feel? Love it/ hate it?

 

Just picked up the complete system. Will install it soon ..

 

Updates?

 

Hi guys, just stop to read the forum. I had a few questions. Are you getting any CEL with the Forced air box? Are you running a tune?

 

And 👋 every one

 

How’s that set up working for you? Did you get any CELS and are you running a tune? I want the exact one but don’t want to add a tune.

 

I've been running this set up for over 5k miles with no CEL and tune.

 

400 miles with the complete Forge setup and no CEL.

 

Can you please post some pictures from the inlet duct? Did you have to cut anything to install that?

 

You still running that set up? How’s it been for you?

 

Alright pulled the trigger on the Forge Intake and Turbo inlets 😯 💵!

 

it’s becoming increasingly harder and harder to not be financially irresponsible with posts like this hahahahaaaaa.

 

I like the Forge air intake & intercooler parts as well. Thinking about them as my next mod steps...

 

Hadn’t posted but received this two about a week ago! 🤗. Ima have a busy Spring..

 

36hrs OT this check, may be pulling the trigger.

 

Here’s my pro tips when installing this intake.

If you’re installing the inlet adapter, do yourself a favor and remove the engine cowl. It will make your life a lot easier and it only take a few minutes. There is virtually no room to work with as you can see from the photo I took. I had it removed anyway because I was installing coilovers at the same time.

Lastly, I didn’t like the tension that was put on the vacuum line in step 12 in the instructions. To be on the safe side I used a 90-degree 4mm brass fitting and a 4mm ID high temp silicone vacuum hose. I don’t know if anyone else experienced this or whether it bothered anyone else, but it didn’t sit well with me.

Thanks for the tips, I have the intake and inlet I haven’t installed yet.

 

I just installed the Upper air box, hard pipe, blow off valve and snorkel (yes, it doesn't fit right or sit well. Not for my 2023 GR Corolla CE. Unfortunately, I have a CEL code. It says that there's a loss of power, also the secondary brake system doesn't work and to check with my dealer. I followed the instruction step by step. I checked everything but something is wrong. Sorry I've just finished, and it's taken me like 3 weekends to do all this at one time. Just for it to not work. Feeling a bit defeated at the moment. I'm not sure how to fix it. I was following all the instructions from Forge and watching videos on it.

 

Sounds like something is disconnected. Did this happen immediately after you started the car? Double check the MAF connector. Unseat it and plug it back in making sure it clicks into place. Double check vacuum lines. Finally, remove the negative battery terminal, wait a minute, and put it back. Let me know how you make out.

 

This is the diagram I was talking about:

I sent an email out to Forge USA a while ago to see if they can fix the instructions, but I’m not sure if that’s happened yet.

wait...is this incorrect? Did I miss your post about this? Because this is what I did and it was the instructions on the website!

I'll check the messages in this forum again really quickly....brb

update: I see. This diagram IS correct and the picture was wrong. I did follow this diagram and it was done exactly like this.

 

Why not Eventuri?

 

My guess is price.

 

I think Cel code issue is fixed, from one of the 50+ videos I watched on the Grrolla. You can also just ride with the code and the engine adjust itself without limp mode (with code showing although). I just want something of quality but either way a bit more power. I need to pay off credit cards and want to get intake after all that is handled anyway. Hopefully get more reviews from this forum !

 

Is everyone running the Forge intake duct having issues with it rubbing on the hood??

 

Yes, that is correct. It damages the part and takes paint off the hood. It happened to me and I saw another person who had the same issue. I am currently talking to Forge and I guess they are sending me a return label? Their customer service is lacking at best…If you had the same issues email forge with pictures. So far they are trying to make it seem like only myself and 1 person had an issue, although it is a product issue as it does not fit correctly on the GR Corolla.

 

This is a great idea. I’ll email Forge to let them know that it’s not only you. I had to put a black foam circular sticker (meant for drawers) on the snorkel as well as the hood to stop it from rubbing. Trying to find a solid solution to it. I don’t want to return it though. Already accepted it as part of an early adopter problem. But you’re right. It doesn’t fit the GRC as advertised on their website. They should tell you it won’t fit properly and will cause rubbing issues.

 

It looks nice, but it will continue to damage the hood as well as the part itself unfortunately, and I just can't accept that. Recently Milltek is handling the operation of Forge US now. I called last week and actually had good customer service! So it does appear they will refund my the $500 for it! Glad I didn't cut that panel, I would have been extra mad.

 

Are you returning the part? Just going to run the stock snorkel? Did they say anything about making it fit for the GRC better?
