TRD cold air intake worth it?

So, all this chit chat about the TRD intake, it makes me wonder how other brands compare? Have any of the other CAI’s been proven to have a performance gain or are they all just add-on noisemakers?

 

+1 very few intakes will provide more than a few HP at best on modern engines. Like I said above I only did it because its cheap and I like the sound of it better than stock.


BTW, putting the intake on the 23 gave me a nice view of the passenger side cylinder head... #$(%&*&$% Toyota what where you thinking? Usually Toyotas and Hondas are really easy to work on with things laid out to make access easy for home mechanics but somebody thought it was a good idea to relocate the exhaust air injection valve on TOP of the cylinder head, so when the time comes I think we will have to remove the entire thing to get to the front and middle coil packs to change the spark plugs. Ugh

Really surprised as those valves where located someplace out of the way on earlier iterations of the 1GR and I remember changing the plugs on the Taco I only had to move some hoses.

 

Does anyone with a 2022 4R have the TRD CAI? I emailed Bam Wholesale asking if they had one for a 2022 4R, and they said that Toyota doesn't list a part number for the 2022. Can someone please point me in the right direction?

 

Id rather spend the money on other equipment. So many other things taking priority over an intake. It also complicates the setup of my snorkel.Yall enjoy!

 

These 4Runners have a CAI factory correct?

 

I am waiting for someone I know with a 2022 to bring it in so we can take a good look and measurements to see if the same one we put in a 21 will fit Good we think it will but until we pop open the Hood....

 

Shhhhh yeah they do it is just the TRD one improves it a bit however they both pull the air from the front right fender well.

 

I’ve done a lot of research on CAIs and nothing has swayed me enough to purchase knowing our vehicles have one already. The only one I seriously considered was the Injen because it draws air from above the radiator as well as the passenger side fender.

 

Thanks for the replies. If any vendors out there want to send one of those, I'll be glad to test fit, document, and photograph everything. I'm not talking cell phone images, I do product photography in certain areas for my retirement gig, and I use a Nikon Z9. Just throwing that out there.

Nice!!! I'm still using the FTZ mount II until I can afford dedicated z mount lenses.

 

I think for CAI, in the past it made sense as many cars it was restrictive or you’d get heat soak. Most cars today are well optimized so even if there are gains, there potentially new risks introduced (more dirt, moisture or actual water risks). For me and my money, I would only modifying this if I’m going the route of a snorkel. You get cooler air, with lowering risk of water, and an added option to put a sock on the inlet when driving in dustier conditions.

 

it fits just fine. I installed mine a couple months ago without any issues.

 

This may have been covered already, so forgive my ignorance - does the filter that comes with the OEM TRD intake:



require oiling after cleaning, or is it a dry filter that only gets cleaned? If it is oiled, is there a replacement AEM type cleanable dry filter that fits the TRD airbox?

Next question - what do these, circled below, do on the stock intake? Apparently they must not do too much, as they are eliminated when installing the TRD intake...

 

The TRD CAI that I been installing Do Not Come with any filter and I am not going to say get the K&N Oil type ones because I have cleaned several MAF Sensors that made a code come up because they were covered with oil film and fine grim So Protect your Engine with good quality Air Filter I been using the WIX - 49350 since it fits very good and I have low pressure air cleaned mine a couple times so far no visible issues.

 

It smooth out Air flow with every rpm change shifting transmission in D making shifting softer and safer for clutch plates.

 

Uhhhh what?

 

Ummm no.

 

A better and more valuable investment would be a tune, such as from YotaWerx Tuning.

 

Every IC vehicle has an AI. Not every one has a CAI. For a very long time 99% of cars had a simple round air filter sitting directly on top of the carb that directly drew in hot under hood air. It was only in the late 80s/90s when FI started to appear that I recall seeing non-round filters and cars with ducted intakes. As late as the early 00s I remember having cars where the intake was ducted to a location that wasn’t really “cold” like for example just to the grill area behind the radiator.

 

Yes it fits fine. You have to piece together the parts but I put it on my 23 without issue.

As noted both the stock and TRD intakes are CAI. The main difference is looks and the TRD lacks the resonators so it changes the engine tone a bit. I did it because I like how it sounds, I think power gains are nonexistent.

 

Lol

 

I have installed them on 5 FJ Cruisers, 6 Tacoma's, 3 Tundra's (2007 and a 2012) two 4Runners a 2020 <--- Mine and a 2021 so that makes 16 total No issues I have all the Part numbers plus I have a person's 2018 Tacoma coming in this weekend to do.

Edit: 1 FJ Cruiser was mine 2 Tacoma's were mine and 2 Tundra's were mine.

 

Since you order the parts separately from Toyota, I take it you source the wire loom, vacuum line, zip ties, and plastic plugs for the air box separately...? Got any photos of said airbox holes that need plugging?

I'm considering this because I like the looks, but also to allow access to the passenger side of the engine. Early on, I had a fuel injector wire chewed by a critter, and it's a royal PITA to get in there for inspections with those resonators in the way.

 

I Order my parts from Bam whole sale Parts (you can too) I go to Toyota Web site Drawing for Part numbers. As for Zip ties I get from a Local Electrical Supply house (Codale Electric Supply) because I want good quality Zip ties (Panduit) that don't break like the cheap ones auto parts stores have.

The Wire Harness Adapter for the MAF I get from Michigan motorsports They have been of a good quality and extra Long at 24 Inches and Yes it cost more than the cheap Ebay ones but since I have to warrant my work.

And the Hole that needs Plug installed I have only seen that twice I do not have a Picture of that hole it is just 1 hole and both times it was the 4Runner Install and the First time I was not prepared for it so I took a piece of 1/8 inch plastic and used my Plastic heat weld to patch it close it was very time consuming So for the second one I just purchased plastic Hole push plugs and put a small bead of Silicone around it first.

 

vacuum hose is a standard item you can find in any auto parts store.

The wire loom cover is also a pretty stand part you can find on Amazon, auto parts wholesalers or at most electronic stores or online at sites like DigiKey. You could probably get away with just wrapping the exposed wire in tape but that doesn’t look as neat.

Plugging the holes is not critical. You can just put a piece of tape on the [edit meant to say side one] one if you want. The bottom one is a gap around one of the rubber isolators and it really should be left open as it functions as a drain in case water ever gets into the box.

 

It is the Little Side Hole that makes the Whistle Noise as for Tape? No can do that will just wash off and does not meet quality workmanship Standards.

The Top Hole in the Lid is for the Filter indicator Put one there.

The "Gap" around the bottom Rubber Mounting Grommet is fine to leave alone and as for Cutting Back the Wire Loom I no longer do that because for a Mere $19 I can purchase an very good extension and just plug it in be done in 10 seconds versus the time it takes to unwrap, separate and Rewrap with time being $$$$ and with guaranteeing my work I just can't.

So no Short Cuts no Tape Jobs No Problems down the road or some where way out in the Boon Docks where I really do not want the Break down to be My Fault.

 

I've not seen that wire harness extension mentioned before, just the separation of the oem wires out of the loom. Do you have a part number for that?

I'm a little unclear - do you install the filter indicator in the top hole, or plug that hole instead?

 

The indicator goes on top of the air box
