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

OEM fit, pattern is not the best
The product fits into your E46 center console perfectly. Locks in place. Great replacement for broken or worn out cup holders. The "carbon fiber" pattern leaves a lot to be desired. It was obviously dipped and the patter is skewed and very fake looking. I wrapped this with a carbon wrap and it looks fine but you might as well get a black one instead. I only gave it three stars because the fit is great as expected but the whole point of buying this one was the carbon fiber appearance which is poorly done.

Perfect Fit for 2008 Prius
I bought this for my 2008 Prius to help with allergens since I drive with my dog often. I wanted something that fit right and actually improved the air inside the car. Installation took under 5 minutes with no tools, and it dropped in without any issues. The build quality feels solid, not flimsy. After installing it, the air smells cleaner and seems to reduce dust and allergens during drives. It hasn’t restricted airflow and is holding up well with daily use so far. Pros: Fit my 2008 Prius exactly with no adjustments I noticed cleaner air and fewer allergy issues while driving Took me less than 5 minutes to install with no tools Cons: A bit more expensive than basic filters I usually get
