About This Product

Protect your 2023½-2026 6.6L Duramax's manifold temperature and pressure sensors from dirty exhaust gas and sticky oil buildup with a Banks MAP Sensor Relocation Kit. A contaminated sensor can cause inaccurate readings, adversely affecting fuel economy and power output. The small billet aluminum device relocates the sensor out of the soot-filled exhaust stream.
Fitment Note

Beginning in mid-2023, GM separated the MAP sensor into two sensors: a manifold temperature sensor located in the former MAP sensor position and a pressure sensor located in a new lower position. Check to ensure you have two sensors located on the cast aluminum intake manifold. See photo.

Why It's Better

KEEPS YOUR MAP SENSORS CLEAN

Your engine’s EGR (Exhaust Gas Recirculation) and PCV (Positive Crank Case Ventilation) systems draw unburnt exhaust gasses and oil vapor into the combustion chambers to lower combustion temperature, reduce NOx, and keep harmful gasses from entering the atmosphere.

LESS CLEANING.
MORE POWER.

This recirculated exhaust gas and sticky oil vapor adheres to the MAP sensors' delicate electronics causing inaccurate readings. This results in incorrect fuel calculations reducing fuel economy and power output.

Reviews

Massive carbon deposits at 13K miles

"I bought this dual sensor relocation kit back in February, but the truck was only a few months old. I just put them on yesterday after my brand-new truck only had 13,000 miles on it. Before I removed the sensors, I figured that they would still be fairly clean. I was wrong. The top sensor was completely clogged with carbon deposits, and the lower one was almost clogged. The CRC MAF sensor cleaner cleaned them up with a little persuasion from my old toothbrush. I highly recommend buying this product and installing it as soon as you are able (it only took about 20 minutes to install)."

— Jerry B. (5/5)

Banks Duel Sensors

"Well made. Couldn’t believe how packed the sensors were at 39000 miles. Can’t wait to check them to see the difference after more miles."

— Lonnie (5/5)

Dual MAP Sensor Relocation Kit

"I installed them on my 2026 GMC Sierra 2500 6. 6L LP5 back in early February. So far they are working as advertised."

— Thomas K. (5/5)

Another awesome part

"This was just one of many upgrades I’ve ordered from banks! This part just like everything else has been a super high quality piece that bolts right up. Super happy"

— Timothy D. (5/5)

Map sensor spacers needed

"At only 43000 miles this is what they looked like."

— Wayne s. (5/5)

Simple & Effective

"Easy Install, looks great, and does what it’s supposed to do !"

— Constantine C. (5/5)

Good to go

"Easy install and looks good. Replaced the stock ones at 25k miles 2024 3/4 ton Duramax and they were nasty, hope these help!"

— Westen H. (5/5)

Works exactly as described.

"Easy install, came with everything needed to do so. Works great! been cleaning sensors every oil change. After having these installed, i just check them every oil change(5000 miles). Hardly anything to clean. So i installed them on all my work trucks!"

— John (5/5)

They are made really nice.

"They are made really nice. Very easy to install. So far they work great no problems."

— Jim F. (5/5)

Hello fine folks at Banks.

"Hello fine folks at Banks. The install went well, directions were clear and easy to follow. Took longer to disconnect the battery's then install the MAP Sensor Spacers!! Truck is a 2026 GMC 3500HD with 2,600 miles. The MAP Sensors were already dirty. Gale Banks is a National Treasure, a wealth of knowledge"

Q&A

Will this void manufacturers warranty?
It depends on your local dealership and how they choose to enforce GM's warranty policies. Our recommendation is to speak with your service advisor. If they indicate that aftermarket accessories are ill advised, then we recommend finding another service center that’s aftermarket-friendly.
