RetroFilter air cleaners cleverly hide an LS drive-by-wire throttle body inside to maintain a low height and classic looks. Utilizing a hidden opening in the base to hide unsightly wiring from the throttle body, this trick air cleaner allows you to experience all the benefits of modern technology and keep the vintage look you want. Pair with any Holley intake manifold with a 4150/4160 square bore flange for maximum aesthetics and performance. The opening is 92mm but any 4-bolt pattern LS throttle body will physically fit. We recommend the LS2/LS3/LS7 style but the L33, L76, and L92 should also fit. *Requires adapter to connect to 4150/4160 square bore flange style manifold - Holley EFI part # 17-93 is recommended. All part numbers in this series: 120-500 - 16-Inch DBW Air Cleaner - Chrome 120-501 - 16-Inch DBW Air Cleaner - Black 120-520 - 14-Inch Dual Snorkel DBW Air Cleaner - Chrome 120-521 - 14-Inch Dual Snorkel DBW Air Cleaner - Black

Sheets
Color: 05 - Dusty Blue, Size: Full
Have been the best sheets I've bought, would totally spend the money again. They feel soft against your skin yet keep you cool and comfortable. Easily fits my extra thick mattress, only a little wrinkles during use. They offer some wonderful colors, went with a dusty blue and am completely satisfied with richness of color.

Exceptional quality and feel
Color: 12 - Light Beige, Size: Queen
I will be purchasing again from Bedsure. I purchased the light beige which is exactly what the color was, like a gentle note of almond to it. Perfect for my bedroom as my master bath has light beige full shower, toilet and sink. I washed them and dressed the bed. The sizing was spot on. My mattress does has a 3" Mike Lindell topper. I would suggest making sure you follow their sizing which I did not do mine just happened to fit and didn't have much to spare either because of the topper.
The sheets feel wonderful to sleep on. They do feel cool on my skin and felt cool out of the package also. I do not believe you would be disappointed unless you just absolutely were in love with the sheets you are on. This set works beautifully for me and my skin loves the smooth texture of the material. I'll be a repeat buyer.

Love BUT they STINK!!
Color: 26 - Forest Green, Size: King
I have the dark green sheets and would give them 5 stars if it weren’t for the fact that they smell absolutely horrible. I am so surprised after reading reviews that more people don’t mention it?! Maybe it’s more prominent in darker colors but I have washed these now 3 different times even with scent beads and still hate the smell. I wish I could accurately describe what it smells like— it’s just not good and for some reason, body heat only exacerbates it and makes the smell even worse and I wake up feeling like a smell like the sheets… which isn’t a good thing.
Besides that, I do really enjoy them. They feel great on your skin, haven’t been pilling near the foot area (which is what makes us go through so many sheets) and I love the color. I wish the smell didn’t kill them so badly for me ☹️
