4" intake pipes

Looking at gn1 performance piece. How is the fit? Is anyone running this piece?

Can't comment on that one, but I bought one of the 4" units from RJC and it was perfect! Just trimmed the end down to fit for the length of my filter. The polish job looks like chrome!

I have a 4", only thing is that the stock radiator hose doesn't have enough room. Might work with a smaller up pipe, but I doubt it. You need to use one of the metal 90 degree bend ones or make one, you can see how its squeezed in my pictures. Looks awesome and fits well though

I have one. I needed to add a plenum spacer to make the up pipe fit right. Without the spacer the up pipe was cocked a little connected to the throttle body.
