EGR removal?
I have a 01 Kia Spectra. First off would removing the EGR help increase performance as this would keep the EGR from recalculating hot gases back into the intake warming up the air.
If it would help does a Spectra have one and where's it located? How would this be done, not to cause driveability problems?

How is it reducing combustion chamber temperatures if it's pumping hot gases back into the intake manifold. It's not so how do you remove the thing on a Kia?
No one has answered me yet on if a Kia even has one yet? smile.gif
I found a vacumm line that comes off the intake manifold and it goes through a valve with a sensor on it into a small canister on the fire wall. Then out of the canister a metal line follows the same route next to the fuel and brake lines and ends up in a large canister next to the fuel tank on the passanger side. It goes into this larger canister then exits it going to some kind of pump then it goes somewhere on top of the fuel tank.
No it's not a fuel line I found and it's not a return fuel line either since Kia's have dead fuel rails (returnless) Anyone have any idea what this is?

That device you found is a gas vapor canister. It collects evaporated gas fumes from your gas tank, and then burns them when the engine runs.
No, EGR valves have not been used since the late 80's early 90's. (except apparently for the Hyundai 2.4L Santa Fe engine).
EGR valves work to keep combustion temps down by "diluting" the incoming air with Exhaust. This gives you a "diluted" mixture of fresh air and exhaust gases, which slows down the combustion event, and keeps it cooler. The hot air from the exhaust also helps the fuel evaporate more completely, which again, slows down the burn, and leads to cooler combustion temps. NOx emissions are at their worst with high temp combustion events.

If I'm not wrong, my car comes with an EGR (it's a Cali. vehicle) and on some of the boards of DSM's I've been to they actually block it off to increase HP. Check this out:No, EGR valves have not been used since the late 80's early 90's. (except apparently for the Hyundai 2.4L Santa Fe engine).

Click on ENGINE, then EGR BLOCKOFF PLATE.

Uh..that example is a 1991, which would be considered "early 90's"
Yours is a 1995, but the engine design is unchanged from the first version in 1991, so it still sort of qualifies.
