Just wandering has anyone else bought an OBX intake manifold? I have a prelude with an h23, got the manifold in hand and realized its missing alot of ****. Not to mention its blocking my coolant pipe that comes from the head and back into the thermostat. I'll get pics up as soon as possible to show what I mean. It also blocks the EGR, IACV, and has no place to mount the throttle cable bracket. Any Ideas.

if you are running all motor, its better to run the stock manifold. the bigger aftermarket one holds a lot of air but it doesn't do anything till you reach the higher rpm range. you have to have a lot of air flow going through the manifold for it to work, if not then its just holding air, which is why it works better when using forced induction.

Oh ok. Preciate it. But I still need help with the other problems with the manifold in order to use it.

just die in a fire for even considering an OBX for an H23. Just use the Euro R or possible the BlackTrax. WTF they crack so easily basically a knock off of Venom. At most Skunk is not bad.

tHE BOLT PATTERNS ARE DIFFERENT BETWEEN THE H22 AND THE H23.

if your h23 intake manifold says p13 on it, which i am sure it does. then they are the same. check it out then hit me back.

On which section? It has three parts to it. I'm saying the bolt pattern isn't the same. Not the plenum or the secondary runners.

bolt patterns are different. the only thing the h23 and h22 stock intake manifold have in common are the butterflies. Hence why you might see p13 on it. other than that they don't bolt up.

Thats what I've been sayin. But I found out theres an adapter plate that someone made to fit an h22 manifold on an h23. Anyone heard of it. If so can you direct to with a link or something.
