Hello,
I want to upgrade to high performance coil packs in my 2014 f150 XLT Super Crew Cab 5.0 4x4. What is the absolute best for this year and model? Will I also need upgraded spark plugs too? It just turned 61,000. No issues as of yet.

 

What else are you or have you upgraded? The stock coil packs are already over what a stock truck needs. You would need to do some serious upgrades before coil packs need to be upgraded.

 

On my '13 Ecoboost, I changed out the plugs to Ford Racing cold plugs and added MSD coils at 94K on the odometer.
The engine idles much smoother and has great acceleration, very happy with this configuration.

Can't compare your engine to one that's naturally aspirated.

Spark plugs and coils at 100,000 miles, stock is more than adequate. No need to waste any $$ on hp parts unless you plan to do some serious engine modifications like forced induction etc......

Hi, I have not made any modifications yet. I am installing a Ford performance air-oil seperator(catch can) this weekend. I just purchased the vehicle 1 month ago from a dealer as a C.P.O. The previous owner lived in Michigan, I live in Orlando Florida. I have found out by meticulously inspecting the truck that the dealer's mechanic did a lousy job on the 172 point inspection they claim was performed before the sale of the vehicle. Based on my findings, I don't trust the dealership. So I am going to be doing an overhaul on the truck. Oil change, air filter, transmission fluid, transfer case fluid, radiator fluid, brakes, etc. I can't get the dealership to give me the maintenance records they have, if any. I bought it with 60,252 miles on it. I am going to assume the previous owner did not do the suggested scheduled maintenance. I will do the work myself and save myself the dealership labor rates$. An example of a lousy job from the mechanic would be a cracked coil spring on the front drivers suspension and a sagging drivers side rear leaf spring. Covered under the warranty, they have ordered parts and they are being replaced, plus new components needed. I have plans after the overhaul to begin adding high performance parts like a Roush cold air intake, Roush cat back exhaust system. I want to add a Roush supercharger and any needed high performance parts needed to compliment it. By what the dealer tells me, these can all be done and not void the warranty if they do the install. That concerns me since they pushed the vehicle through the 172 point C.P.O. inspections. I thought that since I have plans on adding high performance parts, I could change out the coil packs and spark plugs myself to high performance, save some $ instead of the dealership costs. Also add a tuner.

 

Thank you! to those who have responded, explaining that the stock coil packs are doing more than what is needed and would not gain anymore performance, since the truck is bone stock.

What harm would it do to change out the spark plugs now? Assuming the previous owner didn't take good care of the truck, I believe spending the money and time now might be a wise choice in preventative maintenance in lieu of waiting for problems to arrise....like waiting for the oil light to come on before changing it.

 

To further the example the lousy mechanic, I checked the air filter after bringing home my truck and found, though the filter was new; mud, sand, dirt in the air box which I carefully shop vacuumed the filter, surrounding area, and the box itself. I then carefully removed the air box and thoroughly washed it all out. Who knows what is still sitting in the air tubes. I'll have to shop vac that too before removing I guess. I can't imagine that the throttle body and sand will play nice together. It wouldn't surprise me if there is debris down in the coil pack ports too. I dare not let the dealership start tinkering with it before I pre-maintenance it. The truck will most likely go in this upcoming week (hopefully) for the front and rear suspension repairs. I will be cleaning everything I can before they get their hands on it, even going as far as cleaning any rust away and applying penetrating solution on all nuts and bolts associated with the suspension components. My pop taught me...anything worth doing is worth doing well!
If anyone can give some guidance or suggestions that have not been mentioned it would be greatly appreciated!

 

Myself, I would not waste the time or money upgrading the coils. I doubt you will notice any difference and aftermarket units have questionable reliability.

 

Hey raski, thank you for your response! Your input definately supports the the general consensus of leaving the coil packs as is as O.E.M parts. Sometimes not doing anything is the best action. My thoughts are that I am only getting 13.1 average miles per gallon, and i really baby the throttle. Had hopes that an upgrade would improve mpg.
Thanks again, warm regards
