The Grizzly Mass Air Flow (MAF) Sensor is a direct replacement for the 2001 - 2007 GM 6.6L Duramax LB7 / LLY / LBZ, designed to ensure accurate airflow measurement for optimal engine performance.
The MAF sensor sends crucial data to the ECM regarding the amount of air entering the engine, allowing precise adjustments to fueling, timing, and other parameters. Faulty or contaminated MAF sensors, often due to dirty air filters or over-oiled cleanable filters, can result in improper signals, leading to: codes such as P0101, rough idle, poor fuel efficiency, and degraded overall driving performance. Fix your Duramax with the Grizzly MAF Sensor, built to meet or exceed OEM specifications for reliability and durability.

TOO SMALL

Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
