CSF BMW G8X M3/M4 High Performance Front Mount Heat ExchangerThe CSF Heat Exchanger features a 2 Row (vs OEM single row) Core that is 42mm thick with CSF's Exclusive B Tube Technology. Increasing the size of the core and end tanks adds to the overall volume of the system which helps absorb more heat. The more efficient core not only helps dissipate more heat from the system, but also provides better airflow into the radiator that sits behind the heat exchanger. For vehicles equipped with the ZF8 Automatic
The CSF Heat Exchanger features a 2-Row (vs OEM single row) Core that is 42mm thick with CSF's Exclusive B-Tube Technology. Increasing the size of the core and end tanks adds to the overall volume of the system which helps absorb more heat. The more efficient core not only helps dissipate more heat from the system, but also provides better airflow into the radiator that sits behind the heat exchanger. For vehicles equipped with the ZF8 Automatic Transmission, the heat exchanger core specifications were design concurrently with CSF's new Race-Spec Dual Core Transmission Oil Cooler (CSF #8221). The two included Black Rock Guards offer full protection for the heat exchanger (above and below the crash bar), especially when paired with aftermarket "open face" race style grilles. These grilles have become quite popular for performance and aesthetics, and keeping your heat exchanger safe from debris is very important. With well over 100 track hours worth of testing and thousands of miles on the road, you can be assured that the CSF's new High-Performance Front Mount Heat Exchanger has been thoroughly tested and vetted.This Part Fits:

Good value for solar watch
Color: Black/Orange
Nice watch! It is plastic like but it is solar. No indiglo button only a little luminous on the hands so you don't want to wear it in tje dark and expect to check the time. 45mm case is good size for my wrist and the band works good also, Not too long not too short. Overall a good watch with no problems

Do not buy
Color: Green/Black
Do not buy. When I received the watch it did not work and the battery was dead. I bought a new battery and it killed that one as well after about a month.

Inexpensive doesn’t mean cheap.
Color: Black/Orange
After 10 months, zero complaints. Well, I got rid of the horrible NATO strap 🙄. That’s a personal preference. Easy to swap out to whatever you like. Keeps accurate time meaning it’s the same time. I’m not micro analyzing it and the seconds gained/lost. It has a confident look and feel and makes you feel good when wearing it. Sure it’s not high priced but it’s not cheap. Very comfortable, light and not unincumbered. If this is what you’re looking at, you’d be satisfied. Great looking, durable and simple watch. Full confidence.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology.
No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price)
Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh.
Cheap plastic crystal, scratches and mars just by looking at it.
Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one.
Decent lume on the hands, but none on the hour markers even though it looks like there is.
Looks cool.
