- 03 Mercury mountaineer
I have an 03 Mercury mountaineer premier edition with a 4.0 V6 engine. I'm looking into modifying my motor to make it a sleeper. So far I have researched everything so I can get the best HP. I've done as of right now made two three by four inches holes on my stock air box with a regular air filter. You can automatically fill the air intake and acceleration is much better than it was before. I have also clean my throttle body and the idle control valve and it's idling and when you press the pedal you can feel the instant air flow through as in the power feels good. I've added iridium spark plugs with brand new spark plug wires and it feels a lot more better constant recommend oil change every 3 months with high mileage full synthetic oil it has 180,000 MI. So far I've noticed a difference in acceleration top speed and gas safe. The next items will be removing my intake manifold and the oil caps to replace all the gaskets. Also I will be deep cleaning my intake manifold to reduce everything that the years have attached to it. I would get a cold air filter but keep my original box for now as I am looking into modifying an air intake. I've researched and looked for the best option to get a scoop and I will be replacing my windshield wiper fluid container a little bit further back as well as my radiator overfill tank to move a little bit more towards the firewall. It will give me access to the bottom passenger side headlight in which I will cut a hole and under neath at a school with a pipe feeding into a modified air box or possibly get another one from a bigger truck after that exhaust is very important any recommendations on that. Also can I put or ADD electrical radiator fans and do I have to buy a special one or can I use some from another car. I was thinking about adding two electrical fans and should I how long directly connected to where they don't turn off please let me know we'll keep posted
