K-Tuned K24 Intake Manifold AdapterThe K24 Intake Manifold Adapter is a simple and easy way to install K20 style manifold on K24 heads. The recirculation fitting on K24s is typically part of the intake manifold which isnt on K20 intake manifolds. We have designed the adapter to work with all K24 heads including the K24Z Series (R40) heads. This can also be used to install K20 manifolds or cut RBC manifolds on 9th gen Civic si as the water bypass is slightly different and you will not
The K24 Intake Manifold Adapter is a simple and easy way to install K20 style manifold on K24 heads. The recirculation fitting on K24s is typically part of the intake manifold which isn’t on K20 intake manifolds. We have designed the adapter to work with all K24 heads including the K24Z-Series (R40) heads. This can also be used to install K20 manifolds or cut RBC manifolds on 9th gen Civic si as the water bypass is slightly different and you will not need an intake manifold adapter when using the adapter. The adapter lowers intake air temps as coolant is no longer connected the intake manifold. Hondata has shown that intake air density will drop 1% for every 5°F increase in intake temperature. This is wasted power that can easily be gained back by using the adapter. The adapter also features a 1/8 NPT port for a coolant temp sensor commonly used in swap cars.
The Intake Manifold Adapter can be installed either using our spring loaded tab or by tapping the head. We use Honda Bond or similar gasket maker as it provides a strong seal and when using the spring loaded tab when the adapter isn’t under pressure there will be no chance of leak. The spring loaded tab holds the adapter down with constant spring pressure to ensure a tight fit and seal. The other option is using the provided blind hole you can easily tap the head for the second hole. Tapping the head will require a 6.5mm drill bit (to finish the blind hole in the adapter), 5mm drill bit (to drill the head), and M6x1.0 Tap.
Application:
- All K24 Engines
Note:
- When installing that the adapter gets mounted directly to the head (Do Not Install A Gasket Between The Head and The Adapter)

Amazing how fast it works
Item Package Quantity: 1
This works so much better than the prescription cream I got from the doctor. I thought 40% was the highest available. Ease of use and it goes exactly where it's needed. Saw improvements after the second day of use.

Amazing cream to restore cracked skin!!
Item Package Quantity: 1
Cracking of my feet is not the problem. This has been the only cream I found that restores my cuticles!! My right thumb constantly stays dry and ugly. The convenience of applying like a ChapStick is wonderful. and allows me to grab and apply frequently. My cuticle has finally become soft and pretty. :) (Highly recommend)

Absolutely great. I’m a repeat buyer.
Absolutely LOVE this toner. My skin is slightly sensitive and this formula NEVER burns my face. Great exfoliation. No tightness or dry areas. Fantastic for the price and just as good or better than name brand or expensive toners. I’m a repeat buyer. Big bottle and lasts a while. I would highly recommend.

Hard to keep on the shelf
Yesyesyesyes
Imo it's the perfect male equivalent of a Honeypot wipe. It's also rock solid for drying out oily skin but to me it's kind of expensive to use it like that. Easily my favorite out of all the Thayers tonics. The serum is also really good for converting red patches into poppable pimples which then just leave, and the sulfur cream is just invaluable as a leave-on make-up/healing combo. Thayers is good stuff man. It's a billion times healthier than benzoyl peroxide or adapalene and even SA is pretty rough on the skin in therapeutic doses. Thayers does such a good job of balancing herbs and gentle chemicals to provide a uniquely safe yet effective remedy, across the board. The only thing that was a genuine flop from them for me was the rosewater tonic, which smelled like God.
