The difference in power is a complete wash between dyno variance. You're sweating over maybe 1-3hp, which would never be felt.

That said, I imagine the Admin pieces would fair best if you have ported TBs and upper/lower manifolds, otherwise those stock components would inhibit the full benefits of the larger pipe ID intakes. Also probably worth saying that although Admin is pretty pricy, a lot of people here have raised questions about quality/fitment of AAM parts.

Rzg Motorsports makes 3 inch intakes 90 bucks cheaper than admin

Mike Upton makes 3" intakes in the 3-400 range. So, although I have Admin, I'd recommend something cheaper as I doubt you'll notice a difference between them and I believe his have velocity stacks as well, whereas I bought Z1's overpriced "kit" and added them to my setup)

I used the AAM Competition 2.75” CAI on my previous Z it works very well with any bolt on Z the difference between going with a 2.75” vs. 3” CAI would be similar to 1-2 whp nothing you will ever notest or feel. The AAM Competition 2.75” CAI uses 6061 aluminum tubing and K&N high flow air filters. Installation fitment,and quality was excellent and I gained whp and wtq when dynoed.

Ported upper and lower and 3" intake what hp gain I'm expecting with e85 fuel

Currently running stellin gen 3 intakes with 93 fuel

Need to look into mike upton. Never heard of. Crazy the cost of intakes on this platform regardless the quantity

Stillen 323.75 WHP 265.24 TQ
Z1 323.23 WHP 266.37 TQ
Admin 322.46 WHP 265.34 TQ

This was not on a cammed car, so the 3" may actually be worth it w/ the cams. That said, after seeing the post on here w/ all the excess cast/weld inside the Admin intakes, they'd never touch my car. SOHO makes 2.75" intakes and I'd suggest those over AAM. Several people have had good luck w/ the Upton set, which is 3" as well, and I think a couple hundred bucks cheaper.

If you've already spent the money on the Stillens, I'd just hold, personally. As shown above, it's minute and even with the cams, it won't be worth it unless you're absolutely chasing a dyno record or something. The fastest 1/4mi make like 340, which is about par for the course. Nothing extravagant there.
