Nissan Fairlady 350Z have a very unique design above the engine which it have a plenum design, the upper plenum gasket have total 18 screw holes, so how would you like to tighten the bolt in the correct sequence? 

An I found this tighten sequence from Z1Motorsports website which it may useful for those who try to install the new plenum gasket on their 350Z engine.
