2018 Ford Explorer XLT
I wasn't a big fan of the AEM dry flow filters, sounded great on paper but didn't provide any flow benefits over the K&N or paper. I have not pulled out the air filter or airbox for my 2018 XLT, but the EcoBoost engines are ALL speed density... meaning there is no MAF sensor so you can pour oil straight onto the air filter and let it get sucked into the engine without worrying about MAF sensor contamination. As for the naturally aspirated 3.5L V6, it should have a MAF sensor because I can see the airflow vs. voltage table in the tune, but I couldn't find the harness on the airbox on my 2018.

In fact if you pulled the MAP sensor from your intake manifold on an EcoBoost, it's probably soaked with oil anyhow (or some PCV blow by residue).

I did extensive airflow testing on the different air filters, and none of them provided any sizable performance gains on the EcoBoost. They all flowed as much air as the engine needed, even the dirty paper air filter that I used for 3 years that had bugs and acorns jammed between the pleats that I used to run 12.4 seconds in the 1/4 mile. Just my 2 cents, but everyone wants a CAI to make their engine compartment look snazzy, but on the transverse 3.5 EcoBoost CAI kits, they just let in way too much hot air, or don't flow more than the stock airbox.

screenshot of air temp vs. intake temp with STOCK intake on my 2017 sport. Not going to get any colder... CAI's are a scam.

So the take away is... Don't waste money on a Cold Air Intake. Get a quality air filter in your stock box and get more fresh air into the stock box!

I had a livernois Windstorm /airaid cai on my 2017 sport. Noticed a difference in sound but ended up taking it off because I was getting a weird noise from it while driving. From what I remember there was a noticeable change in sound vs stock, but didn't really feel a difference in performance. To me the sport feels stronger with the factory system. The system I had came with a rubber seal that goes up against the hood so I'm assuming it keeps the hot air out.

I think METROPLEX has summed it up rather well. Kinda what I was thinking all along especially for otherwise stock machines. Thank you for the time and effort. Clarence.

Hey Eric - I take it you did not read this thread. I will assume no one will provide you a response due to the 14 pages this thread has produced. I would suggest you read page 13 to make a determination if you will really purchase a CAI. I purchased the Livernois Motorsport Level 2 Performance Package plus some other goodies, but will not be installing their CAI based on reading page 13. Good luck on your modding.
