K&N CAI disables EGR?

[PoohHead]

Probably old news, but I installed the K&N CAI on my '11 Camry SE V6 and noticed that the tubes to the vacuum switching valve are now covered and there is no vacuum modulator any more. So this means no more EGR? Is this how K&N is able to show increased HP?

Also - an idea what the dealer is going to say when I show up for my next free 5K service?

i personally would not like to see anything disconnected under the hood. there are times when the computer will not show a fault code. having the EGR not working can be harmful to the engine. if it were me, and i was working at the dealership, i would make a note in your file that things were disconnected. then when you have an engine warranty issue, i would deny coverage, as you messed around with the anti-pollution devices. this is also known as "tampering"...and it is usually mentioned in ALL warranty paperwork. i'd try and contact K&N about this and see if they have a solution. there may be a "how to connect" in the instructions that you may have missed.

when it comes to warranty work, the dealerships will follow guidelines if something has been "tampered 'with.

you also run the risk of the EGR valve carboning up from non use while the K&N kit is installed, rendering it useless, when you go to put everything back like factory condition when you go to the dealer.

It is not disconnecting the EGR system. I have the intake as well. You cap off two of the outlets on that mechanism that does nothing. You could literally unplug that entirely. The EGR system is still hooked up, just not through that mechanism (essentially bypassing that specific part).

Oh, and if it did disconnect the EGR system you would have a CEL. EGR is taken very seriously because it has to do with emissions. Your idle would also be jacked.

the "o/p" said there was no more hook ups for the vacuum modulator...??

let me inform you of something...if it was PUT THERE, IT DID SOMETHING..!!

if it did nothing....it WOULDN'T BE THERE...

it can be considered "tampering" with the emissions system, or "tampering" with the general running of the engine...go ahead, take the chances of having a warranty voided....i wouldn't.

For anyone who thinks the VSV and VM don't do anything, take a look at:

Idle did go up a bit, but no dash indication of a fault.

thank you for those, and as i have said, sometimes a fault code will not show up....not everything will show up codes.....that's something people will have to remember...

The OP said it disables EGR. I said that is false. I guess we are both right. Bottom line, if you are worried just do not do it. Simple. //End of thread. K&N says it does not void the warranty BTW. They have to prove that caused whatever issue you are bringing it in for also. As long as you go with quality parts (K&N, Fujita, TRD, Borla, Magnaflow, etc) you should be ok with warranty.

Whoa! You guys are way off here. The V6 (only) has a dual air cleaner intake path. The VSV valve regulates whether 1 or both intake tracts are open. It has absolutely nothing to do with EGR or any emission system. I have mine bypassed so both are open at all times. Of course with an open K & N CAI this dual intake system is not used and rendered useless.

According to the one person in this thread it has something to do with it... I agree with you because I said it does nothing and has no impact on emissions, etc. Thank you for chiming in.
