We believe the Ford F-150 3.5 EcoBoost is an excellent engine from top to bottom. Of course, the twin turbo design means the 3.5L V6 also responds well to performance upgrades. We previously wrote an article about the best 3.5 EcoBoost upgrades. Intercooler mods made that list for good reason. FMIC’s offer decent power gains, ensure consistent performance, and numerous other benefits. In this guide, we discuss the best F-150 3.5 EcoBoost intercooler upgrades, benefits, hp gains, and more.
Ford F-150 3.5 Intercooler Designs
At a high level, intercooler upgrades are pretty straight-forward. Turbochargers create a lot of heat since they are powered by exhaust gases. Air also heats up as it’s compressed by the turbos. The intercoolers job is simply to cool the charge air. As such, the purpose of an intercooler upgrade is to provide more effective and efficient cooling. However, there are a few important design aspects to discuss.
The F-150 3.5 EcoBoost uses an air-to-air intercooler system. Ambient air from outside passes over the intercooler to provide charge air cooling. It’s similar to the purpose of a radiator except the radiator cools the water/coolant mixture and an intercooler cools charge air. The 3.5L V6 EcoBoost intercooler is located towards the front of the engine bay – hence the name front-mount intercooler (FMIC).
Anyway, an intercooler is lined with tiny metal fins internally and externally (these fins are connected). As air passes over the external fins it naturally cools the internal fins. Charge air then passes thru the intercooler core and over these fins where it’s cooled. That’s the quick overview. We could write thousands of words on exactly how intercoolers work, but that isn’t the primary goal of this article. However, it does lead us to a few important points: intercooler bar & plate vs tube & fin designs, surface area, and volume.
3.5 EcoBoost – Bar & Plate vs Tube & Fin
Two primary FMIC designs are bar & plate and tube & fin intercoolers. A tube & fin intercooler uses curved edges on the air galleries. This improves efficiency since it reduces air resistance as ambient air passes thru the fins. However, it also reduces the number of fins you can fit into the intercooler.
A bar & plate 3.5 EcoBoost intercooler utilizes rectangular-like air galleries. You can cram a lot more fins into this design, which increases cooling capacity. Bar & plate FMIC’s are also usually stronger and can tolerate higher boost and abuse (such as rocks and other debris hitting the external surface).
Most F-150 3.5 EcoBoost intercooler upgrades use a bar & plate design. They are less efficient and heavier, but common due to better cooling capacity and strength. Some brands, such as Mishimoto intercoolers, use the more efficient tube & fin design. We don’t think there is always a correct answer as to which is truly better. That said, we’ve always run bar & plate FMIC upgrades with great success.
F-150 EcoBoost FMIC Sizing
The next two keys to 3.5 EcoBoost FMIC’s are volume and surface area. A bigger surface area simply catches more ambient air, which in turn increases cooling capacity. Generally, larger intercooler surface areas are a good thing for performance and charge air cooling.
FMIC core volume is also an important aspect. As with surface area, a larger core volume will increase cooling capacity. Many Ford F-150 intercooler mods offer a core volume of 40-100% larger than the OEM FMIC. Where it gets a little muddy is that you CAN go too large when it comes to core volume.
A larger core creates a bigger pressure drop since there is more room for the charge air to expand. More volume to fill can also worsen the feel of turbo lag. If you’re sticking with stock turbos then an F-150 intercooler with roughly 50% more volume should be plenty. Those going for serious power or turbo upgrades may consider larger FMIC’s.
F-150 3.5L V6 FMIC Upgrade Benefits
With some of the background info out of the way let’s jump into the more exciting topics of this article. What are the benefits of F-150 3.5 EcoBoost intercooler upgrades? Who should upgrade their FMIC? Let’s answer these questions in the next couple sections and then dive into some of the best 3.5L twin turbo intercooler upgrades.
Benefits of Ford F-150 EcoBoost intercooler upgrades include:
- 5-10+whp (similar torque)
- Consistent performance (prevents power loss)
- Lower intake air temperature (IAT)
- Better ignition timing
- Reduced risk of engine knock
Power gains with a 3.5 EcoBoost FMIC can be debatable. On a cooler day if you do one quick WOT pull then an intercooler upgrade likely won’t offer much peak power or torque. You’ll probably pick up around 5-10whp towards the top-end of the power band. An F-150 performance FMIC really shines on hotter days, during back-to-back multi gear pulls, or while towing.
These situations are where the factory intercooler is overwhelmed and begins heat soaking. Intake air temperatures get too hot and the engine starts pulling out boost and ignition timing to keep the engine safe. Hotter air is also less dense, which naturally worsens power.
Point is – intercooler heat soak may cause you to lose 10-20+whp in some situations. An upgraded 3.5 EcoBoost intercooler prevents heat soak and ensures consistent performance. Cooler air is also healthier for the engine since it reduces the chance of the engine knocking/pre-detonating.
Who Should Upgrade Their F-150 Intercooler?
We’ll be pretty quick on this topic, but help wrap-up the above details. The factory 3.5 EcoBoost intercooler is relatively efficient for its designed purpose. However, once you begin tuning or modding your F-150 then you inherently create more heat. As you increase boost, air temperatures begin increasing significantly and the factory intercooler is overwhelmed.
Ultimately, there isn’t much need to upgrade your FMIC on a bone-stock truck. There are situations where you may still consider upgrading the intercooler, though. Those who frequently tow heavy loads or live in hot climates may also see some great benefits from an intercooler upgrade.
Upgraded Intercooler Intake Air Temperatures
In the above image, you’ll notice the OEM intercooler shows a 42°F rise in air temperature. By the end of this multi-gear pull, the engine was surely pulling some boost and timing to keep things safe. Not good for power or performance.
With the CVF Titan FMIC, intake temperatures only increased by 2°F. A huge improvement over the factory intercooler. Keeping IAT’s this much lower helps ensure very consistent performance and power – even during multi gear pulls.
Best F-150 3.5 EcoBoost Intercooler Upgrades
Alright – hopefully the above info helps readers understand the purpose, design, and benefits of intercooler mods. With that out of the way let’s move along to some of the best Ford F-150 3.5 EcoBoost intercooler upgrades. Note – tons of great options exist and this is far from an exhaustive list. We simply don’t have time to space to cover every good 3.5L V6 FMIC.
Instead, we will focus on a few intercooler upgrades that we believe provide the best balance of price, quality, and performance.
