K-Tuned K-series Center Feed Intake Manifold - K20/K24
For K-Tuned's Intake Manifold project they partnered up with a long time friend and owner of Magnus Motorsports to design a performance intake manifold to properly fit multiple K-powered cars. They worked with Magnus previously when they helped out with a custom intake manifold on their awesome K20 powered RX7. Magnus is well known in the aftermarket industry for their high quality intake manifolds and they have been designing and welding up their own product for several years now. K-Tuned knew the Magnus design worked, but wanted to collaborate and find an overall manifold layout that addressed the fitment concerns on several different Honda chassis. Clearance to the rad support and the hood were areas that needed attention, so the plenum was lowered and runners shortened a little bit, while still keeping a clean entry angle into the head port. The result was exactly what K-Tuned was looking for, a big plenum, short runner, performance intake manifold that fits numerous vehicles.

The K-Tuned Center Feed Intake Manifold features a very large 5.2L sheet metal plenum shaped in the signature tapered Magnus format. If you look closely at the head flange and plenum base flange, you'll find two custom 6061 billet aluminum pieces that are precision machined using a CNC 3D profiling process. This special CNC process is what ultimately helped make this manifold design possible, allowing us to make the necessary multi-axis CNC cuts. The throttle body bolt pattern matches up to the 86-93 Ford Mustang 5.0L specs, which means our K-Tuned 90mm Throttle bodies will bolt up seamlessly. The custom billet plenum base is a work of art, with four precision machined internal V-stacks that are designed to increase runner entry air speed. We also provided one 3/8 NPT and two 1/8 NPT vacuum ports that are neatly tucked away on the plenum base, and positioned between each runner. The runners themselves, measure 5.75" long with a large diameter of 1.875", and are capable of supplying even heavily modified K-Series engines with plenty of air.

The manifold flange at the cylinder head is available for K20 and K24 heads and is another 6061 billet piece, that maintains proper port entry and injector angles. Included with this manifold is a brushed aluminum K-Tuned fuel rail. It is held in place on a rail mount that is designed to keep the stock phenolic fuel rail spacers in place and accept both stock or aftermarket K-Series fuel injectors. As usual, K-Tuned includes all the hardware, specifically the bolts for mounting the manifold to the cylinder head and the 4 bolts for K-Tuned throttle body use. Last, but not least, K-Tuned placed an aluminum "K-Tuned" badge on the front of the plenum to add a nice finishing touch.

K-Tuned's center feed manifold was recently debuted on the Spoon Sports turbo charged center-drive Civic Type-R at this past 2016 Super Lap Battle (see photos).

Vehicle & Engine Applications:

  • K20A & K24Ax engine swaps into EG, DC2, EK (w/ EG subframe only)
    May fit other chassis's but may require fitment modifications
  • **06-11 Civic Si 2006-2011 (ie. 8th Gen Civic)
  • K20A/A2/A3 PRB style head
  • K20Z3 & K24A2 RBC style heads

**Note: Currently, this manifold fits the 06-11 Civic Si K20Z3 head but is NOT compatible with the 8th gen civic drive-by-wire throttlebody fitment. In the near future, Ktuned will be releasing a version of this manifold with a ZDX (J37) throttle body flange which will provide drive-by-wire throttlebody use.

NOTE: The stock water pump needs to be modified and a K-Tuned AC/PS Eliminator Pulley kit must be used.

Throttle body Fitment

  • K-Tuned 80mm and 90mm TB or any TB with a 86-93 Ford 5.0L Mustang flange
