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 LS3/L92 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 - 7.25" (0° carb flange angle) ? Port Size- 2.59" Height x 1.28" Wide ?

Perfect iPad Case for Kids — Survives Drops!
Color: Purple
I bought this case for my daughter’s iPad and she absolutely loves it. It was very easy to install and feels really durable. The built-in stand is her favorite feature — she uses it to prop the iPad up during her Hooked on Phonics lessons and when watching videos. She also carries it with us in the car, and it has already survived a few drops onto concrete with no issues. The case does not include a screen protector, but I just added one separately and it works perfectly. It is a bit bulkier than my own iPad case, but that actually makes it easier for little hands to hold and carry. Overall, great protection and very kid-friendly design. Definitely recommend for younger kids!

Pretty colors, child proof protector (so far)
Color: Purple
Using for our daughters IPAD which is her learning tablet. So far its been really good no issues with applying it and the colors are super cute. There is a slot for an pen if you have one and the stand functions wonderfully. Only time will tell how well it protects the tablet from tiny hands.

Nice case
Color: Navy/Green
Nice case for my 5-year old grandson. It is sturdy & was easy to put together. As a special needs child it works very well for him however, he does have trouble with the portrait view of the case. When using the portrait view, the unit often collapses as the prop doesn’t always stay in the locked position.
