TRD CAI and Supercharger are not compatible!!

Well the dealer called me today and said they can't install my existing TRD CAI with the supercharger. They said that in their literature it states they are not compatible. I asked why and they said it voids warranty and they won't do it but didn't have a clear reason. I also stated that in the CAI installation manual it shows how to install the intake with a supercharged application. They stated it was for vehicles prior to 05. So long story short I called toyota corporate and spoke with two more people that said the same thing and finally called TRD itself and spoke with two more people and the official answer they gave me is that the truck cannot deliver enough fuel to match the amount of air delivered by the combination of the TRD CAI AND supercharger. So in other words it can run lean. I argued that its wrong that they sell components that don't work together and now I'm stuck with a TRD CAI that I can't use or return. I already had the CAI before I went supercharged. I told them this is a huge screw up and I'm the one who suffers in the end and is out $400. I told them they need to make this more clear. I asked why other dealers are installing them under warranty and they said if something happens that the dealer will foot the bill and not toyota. They also said once they flash the ECU that it is irreversible. So you can never take the supercharger back out unless you buy a new ECU. Luckily I still had the old intake and I dropped it off so they could finish the install and it will be finished tomorrow. I am so pissed off over this whole thing. I realize I could just install it but I don't want lean conditions and warranty problems and I'm not uninstalling every time I need an oil change etc. The engine compartment looks so much better with the CAI. What a shame.

 

add a 7th injector

I don't want warranty issues.

 

If ever you have to take the truck to the dealer put the stock intake on first.

I have 15k miles running the TRD CAI & SC with no problems.

 

Too much hassle. Besides, it should just work without having to play games. Hopefully I can get my money back from the dealer.

 

just put it on after they install youll notice a gain with the CAI. I was running stock intake on my previous tacoma and bought a CAI and what a difference those make with a SC.

 

If you did your own oil changes the truck would never need to go to the dealer. They gave me a year of free oil changes but I'd rather use synthetic oil and do it myself.

Good luck with the dealer and supercharger.

 

If you told them you wanted to supercharge when you bought the intake and they said it would work, then you have a reason to be upset. Otherwise, I tend to agree with the post I quoted.

 

I can't completely agree with that. A CAI and supercharger go hand in hand. Why couldn't they add a 7th injector to fix a lean condition. If warranty wasn't the issue, then the build would be anything but TRD parts and planned out to be sure there are no conflicts. I didn't originally plan on getting the truck supercharged until recently. I bought into the whole TRD line with the assumption that its the safest option because it was designed by toyota. In addition, plenty of guys on here have gotten the CAI and supercharger installed at the dealer without any warranty problems. The CAI installation instructions explain how to install it on supercharged engines as well. Yet the supercharger directions say you can't. This is my problem.

 

So you have a decision to make... the intake shows you how to hook it up, so either hook up the TRD intake yourself or keep the stock intake and get a high flow filter for it. Yeah, it sucks because you want a completely warrantied product but if Toyota won't warranty it, they won't warranty it... Any way you look at it, this is not the dealership's fault, they're just covering themselves and you so you can keep your warranty in tact and not have to eat any costs themselves if there ever is a problem with your truck.

 

How about considering another dealer, OP? either way, good luck.

 

No offense but you're kinda crying over spilled milk, it's well documented on the Internet that the TRD CAI intake is not to be installed on a TRD supercharger if you plan on keeping the warranty intact because like they've mentioned to you already the fuel delivery becomes an issue. Now they do it this way to play it "safe" on their aftermarket performance items just like the ecu flash is super generic to prevent any internal damage to the engine. It is also well documented on the Internet that lots of people use the CAI with the supercharger in place and have no problems but most of these people run other items on their vehicle knowing it could void the vehicle warranty. I for example have installed on my 12' an air/fuel gauge to monitor levels before something breaks along with URD's fuel pump upgrade kit to help with fuel delivery issues. I plan on getting the TRD ecu reflash but also plan on getting URD's engine management which will not only allow me to run a CAI but will also allow me to fine tune for my specific setup. I would suggest visiting xr-underground.com for they have a wealth of knowledge when it comes to performance on our trucks

 

The stock intake is a CAI. You could put the Trd CAI on yourself or with someone or another mechanic. I think the figh flow filter in stock would be more than ample, and would keep you under the warranty. I can see why Toyota would want to avoid granting the warranty for both, they're just trying to protect themselves. The engine is now going to be under more stress then others. It's (probably) going to be used harder. Just like insurance comps, it's just a bunch of odds.

 

I'm pretty sure no dealers will install the SC and the CAI. Maybe some wouldn't care if you brought the truck in with the combo, but I doubt you will see them install it. This is a very well documented issue on TW.

 

You guys all make great points and I realize I sound whiny. I'm just bummed out that they won't work without some sort of hassle in the end. I just want to put it in and move on and not worry. I'm still going supercharged and leaving the factory intake installed. I'll either sell the CAI on here or they might even buy it back from me at the dealership. It only has like 2000 miles on it. Also, the information out there is not very clear in regards to compatibility. I hope this clears up any confusion for others in the future.

 

I just installed a AFE air filter, and I am planning on getting a TRD supercharger soon. Do you think this combo will be OK? Or should I put my stock one back in before the supercharger install. I'm going to have the dealer install the supercharger.

 

Is it a 1st or 2nd gen TRD CAI?... I've heard the 2nd gen doesn't work with the supercharger, But the 1st gen does.

 

See what I mean. Not very clear is it?

 

I assumed the two would work together as well. Sure it's up to the consumer to research, but toyota should have that marked all over the super charger info.

I really want the TRD supercharger for the low end, but perhaps instead of doing their for the masses tune, I'll talk to gadget...

 

I don't 100% agree with that assessment after reading the other thread. It looks like he found some posts on here that say the S/C and the TRD CAI might not be compatible but, in his defense, there are also just as many posts (even in that thread) of people stating first hand that they are running that exact setup. As far as that goes, he did the right thing, he brought the TRD CAI and S/C to the dealer and let them be the ones to tell him they're not compatible. I wouldn't necessarily take things I read on an internet forum to be gospel either. This site is a great resource and full of good, honest information but there are a lot of incorrect statements and opinions on here as well.
