Overview:

The new Holley Single-Plane Race intake manifold were designed with performance in mind. They feature a race bred, two piece split feature that was previously only found on the most expensive race intakes. The manifold will fit GM LS Gen III engines with cathedral port heads and are intended for 4150 style square bore flanged carburetors or throttle body EFI. The LS Race single-plane intake manifold was designed for hi-performance/racing engine applications, 5.3 to 6.2+ liter displacement, and maximum engine speeds of 6000-7000 rpm, depending on the engine combination. This single-plane design provides optimal performance across the RPM spectrum while providing maximum performance up to 7000 rpm. The Holley LS Race manifold incorporates a split feature, which allows disassembly of the intake for direct access to internal plenum and port surfaces, making custom porting and matching a snap. With shoulder bolt locators and O-ring seal, reassembly is simple and precise. Technical Data: ? A-B Height - 7.32" (0° carb flange angle) ? Port Size- 3.28" Height x 1.10" Wide ? Carburetor Flange - Standard 4150 for up to 1-3/4" diameter throttle bores ? As-Cast Runner Cross-Sectional Area - 3.5 in² at the runner entry tapered to 2.9 in² at the flange exit

seriously matte-ifying
Size: 1.7 Fl Oz (Pack of 1)
Don’t judge but back in the day I used to use Avon’s “face perfector” because it REALLY cut down on the shininess of face oil and it also had SPF. It made your face look matte without any other makeup. And I am pleased that this gel is similar. No face grease. It’s not even really a gel—if instantly feels powdery (somehow?) in your hand, thus it’s nongreasy. It leaves your face shine free and protected.

Perfect for a low-maintenance man
Size: 1.7 Fl Oz (Pack of 1)
I have very fair skin and am a low maintenance kind of guy. My entire skin care routine is washing my face and trying my best to remember to put on sunscreen. This is the best face sunscreen I have ever used. It literally seems to disappear on my face immediately after applying it. I sometimes doubt I even got it spread evenly because of how quickly it disappears but it has worked just as well as thicker sunscreens I have used in the past. I would bet this would be great for women under their makeup because it wouldn't feel like another layer.

~ Oily Skin Review ~ (Updated)
Size: 1.7 Fl Oz (Pack of 1)
I haven’t seen any oily skin reviews of this product so I took a shot of buying it and trying for myself. Hopefully this review helps you. I have oily combo skin. It is also sensitive and prone to breaking out. When I shook the product, as instructed, it was not a gel I was expecting. It’s kind of matte gel (almost like a primer), which I don’t like using matte products since it makes me even more oily and the texture of the gel is like a primer. Kind of greasy but soft. However, when rubbed into the skin all the way it surprisingly left my face feeling soft and not really greasy, and even though it’s suppose to be a matte finish, I think because I used my cerave moisturizer first, it left more of a satin finish. After a couple hours I was happy to see that my face wasn’t ridiculously shining! It had a nice glow, and my face (mainly in the T-zone) felt a little bit slippery which I’ll call a win because like I said earlier the product had a bit of a greasy texture so I was expecting to feel REALLY greasy but I didn’t. And another huge bonus is it did not cause me to break out!! Usually my skin with purge on day one of using something new and my skin did not! If you have oily skin I would say try it IF you want to. The price is a bit too much in my opinion, I’d rather spend maybe $15 max on this product but honestly the results, for me, I think I would purchase it again. But oily skin responds differently for everyone so if you wanna try it, I’d say got for it. But if you don’t wanna risk it because of the price, honestly wouldn’t blame you for not trying it. Update: So I have used this for I don’t know how long now. Imma say this much. For colder seasons, my skin loves it. For warmed seasons my face starts to feel extra greasy. Bought the Daily Face liquid, my skin loves it! Have not broken out from it, no white cast. Would recommend not using the gel during warmer seasons.

Reliable
Size: 1.7 Fl Oz (Pack of 1)
I was kinda surprised by the texture, I'd call it a dupe for super goop! Its got that sort of light balmy ish, matte, velvety type of primer feel to it. It actually works well on top of makeup or under it.
