Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) is a California law that applies to all companies selling products in California. Proposition 65 requires warnings if a product contains any listed chemical present above very low levels that are known to cause cancer, birth defects or other reproductive harm. Proposition 65’s warning standards are among the most stringent in the world. Proposition 65 is not a product safety law, but rather a “right-to-know” law. Businesses are required to provide warnings to comply with Proposition 65. These warnings are required to be in place for all products offered for sale in California.
There are over 800 chemicals on the Proposition 65 list, which is administered by California's Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. The list includes naturally occurring and man-made chemicals. Proposition 65 warnings can be seen for a wide variety of everyday consumer products, including Automotive Performance products, and warnings can be seen posted throughout California in a variety of establishments such as hotels, restaurants, automobile dealerships/repair shops, and retail stores just to name a few.
To comply with the requirements of Proposition 65, this warning is present on all products sold by MPT.

The Turn Offroad IAHL-M4B Roof Headliner Kit is a purpose-built interior upgrade designed specifically for the 2021–2026 Ford Bronco 4-door equipped with the OEM hardtop. Engineered using 6mm automotive-grade EVA foam, this kit transforms the factory roof into a more refined, insulated, and acoustically improved cabin space. It is designed to reduce harsh wind noise, minimize roof vibration resonance, and significantly cut heat transfer from direct sunlight. Beyond performance, it also elevates the interior appearance with a rugged topographic-style texture that gives the Bronco cabin a more premium, adventure-ready finish. This is a direct-fit enhancement that delivers noticeable comfort improvements without altering or replacing the factory hardtop structure.
Installation is considered easy and beginner-friendly. The peel-and-stick design eliminates the need for drilling, cutting, or specialized tools. Once the roof surface is cleaned and prepped, the precision-cut panels align directly with factory hardtop sections. Installation can typically be completed in approximately 30–90 minutes depending on prep time, with many installations finished even faster. This is a straightforward DIY upgrade suitable for most vehicle owners.
This product is supported by manufacturer warranty coverage through Turn Offroad. Warranty terms generally cover defects in materials and workmanship under normal use conditions.

The SCT tuner in combination with MPT tunes and support is an absolute game changer. It facilitates an easy DIY way to install your tunes, datalog and select gauge layouts to monitor temps, boost, timing etc in real time. It’s a great little tuner.
I was having trouble deciding on who to use for a tune on my 2023 Powerboost. I sent messages with questions I had to each place and MPT was by far the most responsive, knowledgeable and helpful. So I decided to use them. I went with the 93PR-X and a daily towing tune. The tunes are easy to install and the difference in power and shifting is day and night. My truck now runs and drive the way should have from Ford. I highly recommend MPT for all of your tuning needs.
Very pleased with the tune and customer service. I've tried canned tunes, 1 other custom tune provider. I've never had a tune simply work the way it should right as I leave the driveway.
Much smoother ride and a lot better when towing my boat. It seems like there's more control when towing.
I heard alot of good reviews about MPT tuning and I definitely wanted to see the difference from their tunes compared to the basic tune from SCT BDX and mannn was I blown away how much more aggressive and smoother my transmission shifted with PRX-93 tune and There customer service is phenomenal sent an email about revision my tune late at night and by the next morning I had my tune back so I would definitely recommend any one with the 2.7 V6 to get their tune you won’t regret I promise
