    I have been seeing write ups about removing the air box silencer for some added sound/“cheap” lol performance mod. I am fairly new to the sho and would appreciate any help to do this on my 89 mtx. Wether I do it or not is another thing. Direction and pictures if possible would be great.
    Thanks in advance

    Have you owned your car long? I'd be suprised if it's still there. Removing the silencer is one of the first things done to these cars. I haven't had a SHO with one in a while.

    I have had mine for not too long now. Maybe 6 months I’m pretty sure it still has everything in tact. Honestly my 89 mtx is next to a new car. I purchased it for 2k with 53000 kms on it. I haven’t even reached the 60k maintenance yet. The only thing wrong with the car was the headliner edge by the to of the rear window was peeling. A good engine clean and detailing are in store. Thus far I am quite a satisfied sho owner.

    I recommend it. Whoever owned mine just slapped a cone filter on it and it sounds great!

    Don't bother It doesn't even do much for the sound. I luckily got the removed cone with my car and it's a part of the stock parts that go with it.

    Reach up inside the fender well and pull it out.

    I took my cone out decades ago. It is a little louder at least to the driver. Did not do comparative dyno pulls; I figure the K&N panel is a performance improvement. I wouldn't go cone filter unless it is also drawing from the fender, as underhood heat is a performance sapper.
    Your car sounds very cherry! However I would suggest that you should make sure that the 60k is done soon if it hasn't been. All of the various seals and belts are old as the hills and you're asking for trouble leaving those in. Likewise, the water pump may be worth doing to prevent the dreaded leak onto the sensor syndrome. And check out all of the other gaskets while the work is being done.

    I wouldn't worry about the 60k on that 89. I would do what I do with all used cars: all fluids, belts and hoses. If there isn't any leakage, I wouldn't bother with the water pump. There's been debate for years about that "leaking water pump" theory, but unless you have a reason to get into the front of the engine, I would just leave it alone.

    Over time, starting a parts collection of things like the crank sensor and a water pump, as finances allow, as they aren't cheap.

    Another good thing to do, as time allows, is to unplug/plug every connector you find, cleaning if needed, and filling with dielectric grease. Especially the four in front of the radiator. It will help prevent weird electrical issues down the road.
