on the 9xauto site it says in order to begin the proces for a nitrous system you should first,,,,,

[ol][*]Change all fuel injectors to NEW and not rebuilt.[*]Change the Oxygen sensor to a NEW one[*]Change the fuel pressure regulator and fuel dampner. If your engine oil smells like fuel, it is further proof of malfunction.[*]Make sure your fuel filter is new[*]Buy a high performance ignition coil and plug wires (do not install funky looking plugs. OEM works the best) Beru silver "Silverstone" plugs are the best choice.[*]Change gear lube oil in your manual transmission to SWEPCO high grade racing blue oil[*]Change your paper filter box to an open K&N system with header’s heat shield installed[*]Install a Throttle response wheel to your throttle body[*]Install a new injector boot as well as new rubber hoses running to the manifold. Old rubber is usually hard and brittle. Microscopic cracks leaking air will lean out your mixture creating "underload" reducing engine’s pick up power. [/ol]

some of these parts are pretty expensive like the oxegyn sensor, the reason i am questioning this is the fact that the site that mentions this also sells the exact products,

are they trying to push more on us than we need to up there sales? or are these all genuine products that should all be replaced prior to a nitrous set up?


thanks guys

 

Considering the age of the car, it would be wise to do most, if not all of those things they recommend. However, there are other options to their list that could save you money. These items (O2 sensor, injectors, fuel pressure regulator, etc) are sold elsewhere. Check prices, do your homework.
