Toyota Tacoma Cold Air Intake

I have an 08 Toyota Tacoma TRD Sport prerunner double cab. I am thinking about getting cold air intake on mi truck. Is there one i can get that dosent make a lot of noise when you acclerate? what does it look like? Where do u get it? I am new to this forum.

 

You are lookibng for an impossible product for our trucks.

 

what ur looking for is called magic it comes in the form of pixie dust. If you find it u hold the right to rub it in everyones face...

but seriously not alot u can do in this case that wont add sound, best u can do is go drop in a high flow filter in the stock set up. the gains r up to debate.

 

We're gonna have to duke this one out one of these days chris.

I'd love to have a good in-depth debate/discussion on this. I think it would open a lot of insight on both ends and give us an opportunity to see things inside out.

Personally I'm all for an aftermarket intake, as it will provide great gains in the right scenario. While not all intakes are created equal, they can all be used with other mods to show positive gains.

Now saying an aftermarket intake is necessary in all situations is not entirely true. Depending on what your looking for, a drop in filter could very well be a better decision then an aftermarket intake.

 

20-30rwhp on a TRD s/c is just a tad more the a 'little' gain.

If you could, shoot me a PM with the CAI and dynos that you've tested. I'd like to see what you've seen.

Because our ECUs are a learning computer, it will take some time between mods to actually see the gains. Changing an intake and running back to back runs probably won't net you much of any gains on our trucks, simply because the ECU hasn't relearned its map and adjusted.

Plus when it comes to volumetric efficiency, the easier it is to come in and the easier it is to go out, the more power you'll make. Our trucks don't really benefit from the 'cold air' aspect but more of the less restrictive intake tubing.

 

I installed a TRD CAI on my 09 last week, and I am very satisfied with the results. Definate imorovement on acceleration without hesitation, and the sound is perfect. Not loud but just the right amount of low rumble. I love it and can't wait to install my TRD cat-back next. Hope this helps.

 

but don't you think though that most people want quiet vehicles and if 15hp (doesn't trd advertise the cai at something like +15 hp?) comes at the expense of much more noise then they wouldn't want it on stock? how can it be advertised at +15 hp or + anything if it doesn't do it?

 

well crap. that's retarded. well, guess i just saved 350 bucks.

 

The high hp gain I saw was going from the stock intake to the TRD intake (IIRC) on a TRD supercharged truck. I'm looking for the dyno sheet now, and will post it once I find it again.

Here is a dyno done by a 3rd Party, comparing two aftermarket intakes (TRD2, and the aFe Si Stage 2) to the stock intake.

+12rwhp/+13ft-lbs, which is real close to what is advertised.



The intake runners play a huge roll in the VE, and the TB will determine the volume of air coming in. But the motor is still a big air pump. And because the intake stroke is based on vacuum any restriction through the intake system will have a negative effect.

In regards to the engineering, performance is sacrificed for ride quality (quiet intake) and emissions. So because the system is designed to meet those requirements first there is still untapped power to gain if you're willing to sacrifice the features.

 

ok guys thanks for all your posts. Can i just change the black plastic tube to a metal one and upgrade to a k&n stock filter? what will that do?

 

I wouldn't recommend that.

MAF accuracy is another big part of aftermarket intakes. The reason the K&N for the 3.4L was so bad was because of the bad MAF accuracy. If your on a budget a drop in filter is your best bet.

 

All i can say is, i went from a k & n drop in to an AFe cai and big difference! It made a big difference and not just in sound. Sounds good imo and now i have the URD maf. sensor calibrator and it's even more WOW! I don't have a dyno sheet but i could definately feel the difference. So i would say i had to have gained a few ponies?

 

is this from an otherwise stock truck or one with other mods? also, is "TRD2" the "new" TRD intake? i'm assuming this is second gen truck? it makes sense that cai would make a bigger difference with s/c than with n/a because that's the whole point.

 

Whats wrong with a little noise

 

I'm going through old posts like crazy because I'm trying to figure out the best next steps for my truck. The Taco is a learning computer!? what!? what does that mean? I should never have to replace the CPU because of upgrades? I have an 05 prerunner. Would love to hear more

 

I do know when running a K&N filter be it for the stock air box or cone filter on their K&N CAI that a dry filter makes more hp than a oiled filter . I used to help a friend of mine with his dirt track car and with a wet K&N filter laps times fell off 3/10ths a second . A dry filter with a sock the opposite , lap times were noticeable faster


On my 02 double cab with a supercharged 3RZ 4cylinder which I'm currently @ 4.5psi and will be going to a 8psi tune I'm running a K&N CAI and running the filter dry with a sock and can definitely notice a difference over the wet K&N I pulled off
