Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Cleaning the UIM and LIM

I searched this topic and noticed that doing this helps with horsepower and helps the engine last longer. How would I go about doing this? Right now I want to try getting my newly replaced engine working 100% before I continue on with the mods. So far resonator removed and custom air intake with heatshield. Also, how would I clean out my air intake and throttlebody? Lastly, would replacing my plugs and wires with better ones effect my engine noticeably? All of your info and tips is apreciated.

ALSO...I hear people with svts can chirp second gear. Can't seem to do that on mine. Is this a sign I need to do the above maintenance or get a new clutch? Thanks again.

I can chirp them easy (w/o powershifting) with only 170hp, and 195 profile tires, good technique should let you overwhelm your wider (probably) tires with 30 more hp. Also, I have a brand new (7k) clutch, what shape is yours in? And how do you feel about the no-res sound? I'm thinking of putting on the SVT dual exh, but taking out the res might come first, and I've hear it sounds too raspy for some. I like that my car is a sleeper, but a **little** growl would be nice.

Get some Berrymans B12, and pour it into the manifolds when they're off the car. For the throttle body, a spray can of Berrymans B12 works quite well at removing the gunk built up.

For spark plugs, you are best sticking with the original Motorcraft or Autolite plugs. You have several oprions when it comes to plug wires, although the factory wires are generally pretty good.

... and my car will do a little chirp into 3rd if I shift right don't do it all the time though, unless you plan on rebuilding your transmission soon.

How can you tell what condition your clutch is in? Any good tests? I was thinking getting a new clutch anyway since there are a little over 50k miles on the one right now. Thinking about the spec stage 2 clutch. Seems like it would be a good investment.

hondas_for_breakfast...I personally like the sound of the svt exhaust without the res. Its only raspy for a minute on a cold start up and the drone isn't too bad. I can deal with it. When the car idling, you can hear a rumbling noise from the exhaust. Much better than with the resonator. highly recommended.
