Fits 2020-2023 Bmw B58D; Matte Carbon Fiber Engine Cover-D590-0004Borrowing on classic engine valve cover elements from yesteryear, the Dinan B58D engine cover takes those queues and incorporates additional elements to form a transformative engine bay dress up piece like no other. Like the ever popular and lusted after E36 E46 Dinan carbon fiber valve covers of the past, the G chassis B58 engine cover mimics the BMW power stripes but with a Dinan twist. Beyond the legacy homage, the 2x2 matte twill carbon fiber base
Borrowing on classic engine/valve cover elements from yesteryear, the Dinan B58D engine cover takes those queues and incorporates additional elements to form a transformative engine bay dress up piece like no other. Like the ever popular and lusted after E36/E46 Dinan carbon fiber valve covers of the past, the G chassis B58 engine cover mimics the BMW power stripes but with a Dinan twist. Beyond the legacy homage, the 2x2 matte twill carbon fiber base gives way to opposing gloss carbon fiber and white painted accents among the cylinder count callouts. This small touch adds visual intrigue to an otherwise largely feature deficient landscape. The conflicting finishes also carry the added benefit of tying together elements within the space that may be of the secondary finish for nearly limitless visual versatility in a single piece.
Features:
- 2x2 matte twill carbon fiber with opposing gloss carbon fiber and painted white accents
- Power stripes featuring Dinan – an homage to OEM and legacy Dinan engine/valve covers
- Direct replacement of factory engine cover
- Lighter - OEM cover: 4.1 pounds vs. Dinan Cover: 2.9 pounds
- Grommets included for quick and easy installation

High Quality
My husband is deficient in magnesium and these by far looked like they were of the highest quality . Not sure yet if they help him sleep better but will be purchasing them again.

Better sleep, better mood
This definitely helped my mood and sleeping. It literally changed my default. The only electrolyte that can pass the blood brain barrier. I recommend.

For better sleep and consultation and calming effect.
It seems to work for me, it makes me calm but energetic, plus I sleep for 8 hours since taking it.

Not working for me 100%
Still not sure about how this magnesium affects me. I have only been taking one tablet an hour or two before bedtime. Seems like sometimes I can’t go to sleep after taking it, charges up my brain. Other times I sleep but have crazy dreams. Maybe it works for some, but not others. I’ll try to finish the bottle, but the lack of sleep after taking the Magnesium L-Threonate makes me hesitant to continue some nights. That’s mainly the reason I purchased this brand to include the reviews.
