This is my picture. I would like to ask you how to reduce the knock. Thank you

MISHIMOTO SILICONE INDUCTION HOSE Intake K&N Filter Original Air Filter Box

Exhaust pipe head section skunk2 alpha middle and tail section MUGEN POWER exhaust pipe

The original engine K20Z3 abolished the reverse balance shaft and changed it to K20A red head engine oil pump

Where is the knock occurring?

Can you post a datalog with the knock you are concerned about?

What octane fuel are you running?

Fuel 98 octane

Ok, I'm recording the data log of the percussion sound, thank you
