Hello,
for the AdminTuning 350Z VQ35HR 3" LongTube Cold Air Intake Kit how does it stand with Z1 Motorsports 350Z / G35 Cold Air Intake Kit with the Upgraded Velocity Stacks?

Thanks.

 

no matter what you will need a tune

 

That's what I'm going to do. I'm trying to see which one has better performance. I was reading online and those two cold air intakes are the best performance WHP for vq35hr.

mod on my car:
exhaust header
exhaust system

 

While I can't compare specifics, I'm sure you can dig through his social media and compare dyno numbers/ modifications from the posts. The hp increase is likely similar in range, however, if you're exhaust is already completely free flowing adding more air with larger diameter piping would probably make the most sense. Whereas the Z1 intake I believe is still the same diameter as stock.

I don't have experience with the Z1 pipes, but I will say expect to trim/grind a lot of plastic around the front radiator support, etc... to fit the 3 inch piping and air filters. You may also run into fueling issues at higher rpm with the 3", but there's no real way to discover this until you're in the middle of tuning, just something to keep in mind. I had dyno tunes before and after the 3" intakes, and I believe the car gained slightly less than 20hp at the top of the powerband with just the intakes added onto an already free-flowing exhaust.

 

thanks.
