I did a quick search and didn't find many threads on actually changing them, but then again I fail at google and internet searches. Can I do the plugs, thermostat and tune in under a day? This is my only vehicle. Thanks

That should be easy. These are by far the easiest plugs I've ever done on a transverse mounted engine. It's even easier than a few standard mounted engines. It only required a plug socket, a couple extensions and a universal. Nothing needed to be removed to make room for the plugs (some do remove a couple things but I worked around them). The thermostat is also pretty easy to remove and install. Even taking your time and working slow, it should be less than a day.

AUTOZONE sells a spark plug wrench that is one piece and had the socket/extension and magnet all in one. Remove the coil pack bolt (10mm) I believe and work one at a time.

Remove the strut tower cross brace and set aside. That is probably the biggest tip that helped me out.

1. Remove strut cower cross brace
2. Remove coil pack bolt. (One at a time)
3. Insert socket first then insert ratchet and loosen as necessary. (Again one at a time)

4. Install new plug in opposite order. ............Don't forget the Anti Sieze for the spark plug threads.

5. There is one vent tube that you will need to loosen and set aside but you will see that when you lift the engine cover off. This will help with spark plug removal, especially rears.

Also recommended is use of some compressed air for the spark plug chamber preferably BEFORE removing the plug. If no compressor available the can of compressed air that you use for computer keyboards.

Replace plugs coil packs and bolts as necessary.

Re install strut tower cross brace and tighten bolts as necessary.

Front plugs are fairly straight forward same procedure as rear only nothing else to remove.

If you need a photo of the one piece socket/extension PM me email address. They have different sizes but I am about 99% sure ours are 5/8"

As for the tune Yes should be able to be completed I. A few hours. Biggest part is to be patient and read the instructions closely. It took me two weekends but I did the plugs thermostat CAI Kit one weekend and the tune and 3 bar MAP sensor the other.

Every step up to the 3 bar MAP sensor can be done prior to tune.

DO NOT install 3 bar MAP sensor until tuning files are loaded.

Allow a minimum of two to three full tanks of the octane rating fuel the tuning file requires PRIOR to installing tuning files. Example of you are getting 93 Octane (best results) but order tuning files for the predominant fuel in your region. If 93 available then run minimum of two to three full tanks of 93 octane through fuel system. This procedure will allow the ECU to adapt to new octane and not be as quite of a shock to the system when tune is loaded.


Recap: A/Z one piece spark plug socket.
Since your already there also get a small packet of anti Sieze, radiator hose grease and in my case some thermostat housing sealant. Optional but I recommend. The packets should be available at the counter. Optional but also recommend is a small pack of die electric grease for the spark plug/coil electrode tip.

Some DexCool anti freeze....(Orange). Make sueee you get the Ford Approved type. Expect to lose somewhere around a quart.

Note I didn't say thermostat and spark plugs if you get the LMS Kit they are included.

Remove strut tower cross brace

Remove rear plugs one at a time.

Re install strut tower cross brace and bolts.

Front plugs same steps as rear one at a time.

Thermostat

CAI Kit

Tuning files from laptop to tuner

Tuning files from tuner to vehicle.

Three bar MAP sensor

Enjoy. Shifting will probably be a bit harsh for about a week especially with WOT acceleration but should smooth out after that when transmission learns the new driving habits and tune file parameters.


REMEMBER: With tuning files installed on vehicle that is your new MINIMUM Octane rating for future fuel purchases. You can go UP but not DOWN. Example 91 tune.....you can put in 91 or 93 but not below 91.
The tune works I picked almost 60 HP......(AT WHEELS) and 72 lb. ft of torque.

Wow thanks for the detailed quick response. I think ill put the intake and thermastat in tonight, plugs tommorow, then fill up with 93 and drive a week. Ive been putting nothing less than 91 and about a third of the time 93 so to play it safe ill run some 93 for a week. Lucky for me 93 octane is plentiful in saint louis

Thanks 'SEL. I just received my tuner last night and will be sending for files today. You've done a lot of excellent work, and I just wanted you to know it's appreciated.

No problem the LMS kit is pretty user friendly even for a first timer like myself. LMS provides very detailed instructions and are available for tech support. Jamie and Anthony both helped me out and prevented me from screwing it up. Protected me from myself as it were. Remember every step but the 3 bar MAP sensor can be installed prior to the tune. Take your time and you should be fine.
