Ok, call me an idiot but why did everyone do this again, was it just for weight reduction? I havent read anywhere if it really helped hp gains or performance? Once again if I missed it let me know.

weight, and it reduces the amount of popping/backfiring you hear with an aftermarket exhaust. No HP benefits though.

It sounded to me like the backfiring increased when the KLEEN was messed with? I mean isnt the clean there to catch unburned fuel and make the engine burn more efficiently to meet cali standards? I would imagine by removing this it would increase the chances of backfire. I mean isnt a backfire fuel catching inside your canister causing a audible pop as it burns or creates a small explosion?

Sort of Frank, The only thing the AIS(Air Injection System) does is pump fresh air into the exhaust just after the exhaust valves. This allows any unburned fuel leftover from the combustion process to mix with the fresh air and burn in the pipe. the stock pipe has enough baffling so you don't really hear the backfiring, but with an aftermarket pipe you do. Installing block off plates stops the flow of fresh air into the exhaust and reduces the amount of 'afterburning' that occurs in the exhaust pipe.

You do need some vacuum caps even if you are installing the block off plates.



On my CA model there was a small 4mm (0.160") nipples coming out of the Cyl#1 throttle body and the Cyl#2 throttle body (2 total) that I had to plug. You can use 1/8" vacuum caps here. If memory serves me correctly these were attached to the charcoal canister.



Also there is the large nipple 15mm (0.590") coming out of the bottom of the airbox/throttle plate. You can use a 5/8" cap here. This nipple supplies air to the air solenoid that is removed with the installation of the block off plates.



Hope that helps

Omega all of this is mentioned in the very beginning of the thread.

My reply to SMbowen was mearly to let him know that the DK plates do not require any vacuum caps BUT if someone is using the exhisting OEM plates then yes they will require two 5/8" caps.

I Bought Some Block Off Plates From Ivans Performance And They Are Top Notch, He Stated That The Fi Light Will Come On.. A Resistor Is Needed To Prevent This. It Should Be As Simple As Taking A Meter And Read Across The Valve Poles And Going To Radio Shack For The Resistor.. Has Anyone Done This Yet? If Not I Will This Weekend.

I installed the Dan Kyle block off plates, and the FI light didn't come on.
