Adding some growl.....

My mech was kind enough to loan me his previous air filter and now the car has added growl during throttling.....

At the same time.....hehehehehehe.....there are some additions that are best left to your imaginations or observations.....

So here goes.....HKS Filter (on loan) hehehehehe.....

Fairlady Airflow Sensor which unfortunately flows so much air that the engine is knocking and I can't run a high boost.....

That said, the oil filter relocation kit has been there when the oil cooler went in.....

Can't wait to dynotune the car.....
