PZEV is "Partial Zero Emissions Vehicle" - a pretty strange combination IMHO but I guess they were desperate for another name to use (grin).

I've heard the "Partial Zero" bit refers to the emissions when parked. They had to change to a steel gas tank from a plastic one 'cause some fumes leach out right through the plastic.

The PZEV changes I know of on my 2.3 either help or don't hurt much.

Steel tank - rather have no rust plastic, but even those can have issues.

Better fuel injectors - multiple holes in tip for better atomization of the fuel. A good thing, clean & efficient burn also yields good power.

Air injection to exhaust - not a big minus.

"Lifetime" air cleaner - used on all from that model year. Often replaced with a CAI or SRI system since they're cheaper than stock replacement. (debate on actual cost, advantages/disadvantages is a separate issue)

At the KY FocusFest it was competitive with stock ST's/SVT's in the Drags on SVT wheels/suspension, so I don't think the PZEV changes are a big disadvantage.

There's a basic list of variations for ya, '09 2.0 variations are similar AFAIK.

Cheers!

I have a 2005 PZEV Focus. I have yet to remove the second catalytic converter that is further downstream, but I have messed with the intake. What I did was tear out that big box thing with the piping up over the fender like you were talking about. Then I simply attached a cone filter to the end of the pipe that was left. I later got a tune that is supposed to help, but I noticed no difference in power or gas mileage. I will admit that when you first start the car, it is a little annoying until it warms up. It sounds like a vacuum cleaner sucking in air. But once its warm you can't hear it... Unless you step on it!

My car is an auto and made 110 HP and 113 Tq to the wheels with just that mod. I later deleted the hose that goes from the valve cover to the intake pipe. I blocked off the hole in the intake tube and put a breather filter on the valve cover. I ended up losing 1 hp and my car always smelled like oil, so I took it off. I've also done an EGR delete, which worked miracles for mid-range power. So between the EGR delete and the intake, the car runs pretty great!
