Ok, I have an 06 ST and I'm unsure as to what direction to take. I drive for a living so reliability and warranty are of utmost importance. My fiance is a service mgr for a ford dealership so I have a bit of wiggle room on the warranty issue. Right now I'm leaning toward the Marcy Motorsports CAI, Borla 2.5 catback exhaust and those copper plugs everyone is talking about. I'm in Ohio so smog isn't an issue, but I would like whatever I do to be easy to undo just in case our politicians throw us a smog curveball. I am also intrested in Mr Marcy's future intake manifold and the stage 1 cams. Suspension wise, I am looking at either the eibach pro or svt with stock dampers. I do not plan to go up in wheel size, but I may upgrade to 215/45/16s on a 16x7 or 7.5 wheel. Down the road I might do gears, torsen, clutch, and lightened flywheel.Any comments, ideas, or suggestions are welcome. Thanks

That's sounds like a perfect list. I'd also throw in a balance shaft delete as it removes mass that is rotated by the crank and in my experience doesn't really affect vibrations external to the motor and perceived by the driver. IMHO it was actually smoother. You are also able to run another quart of oil over stock, more oil is definitely a good thing.

Sounds like a perfect list to me too!

Last week I did the MM BS delete and I have noticed a marked increase in vibration. Maybe some of these D3.2L's have better internal balancing than others?

The week before the BS delete I switched to the Autolite 104's and my ST made power sooooth as silk. Now you can feel it vib a idle by putting your hand on the dash and also a bit in the steering wheel and gas pedal. Worst is the clutch -- If I leave my foot on it much longer than normal it starts to tickle my foot!

I am acutally quite torn. Sometimes I miss that almost liquid smooth power delivery! Yet othertimes its as if I am actually feeling the real engine, as if I've awakend a bit of monster. And it's telling me "see I am alive -- please feed me -- feed me intake, cams and exhaust -- set me FREE!"

Oh well, my main motivation for doing the MM BS delete was to gain the extra quart of oil capacity, so I guess I'll stick with it for now. If anyone has any hints or tips or thinks I've missed (or messed-up) something please let me know!!

Also, FWIW the MM BS Delete kit is still on sale at just $19 (Special pricing ends October 31, 2006).

you wont void your warrenty enless the part you put on your car proves 100% that it was the reason of why you need warrenty work. i got cai, exhaust, tune and tb and havent voided mine. only real time theyll void it is if you put internals in it and still if you get ford to put them in for you they wont void it. put if you put your cai on wrong and it causes your motor to blow then yes warrent wont cover it.

My fiance is a service mgr for ford and I assure you, it is not that cut and dry.

The individual dealership has a LOT to do with it. The bad ones don't want to do warranty work due to the lower labor rate. The good ones know that if they are good to their customers and get everything warrantied they can, it will pay off in the long run with higher volume, not to mention that when said vehicle is out of warranty, the customer will still bring the vehicle in at the non warranty rate because they TRUST them.

I'd be a bit careful, a guy I know had his M3's warranty voided because they claimed his CAI voids warranty since it forces more air into the engine than it was designed or some crap along those lines.

Naturally, we're stuck with German dealers and service centers but I'd double check before putting anything in.

It does depend on the problem. I took mine in for a clutch issue recently, and asked the service manager if my CAI and exhaust would void the warranty. He said it depended on what the problem was. For example, if the clutch disc was disintegrated, or if a spring had come loose from the disc- then Ford would say that the extra power caused by the aftermarket parts was at fault. However, if it was a bad master cylinder, then that would be covered under warranty.

that list looks good. but i dont know about the BS delete. if i could go back in time i would have not done it. perhaps my lower engine mount give more vibration but still i think its not worth it. vibration is the issue with me and raid quality
