Review: 8/10 for a boosted engine. - Intake looks fairly good quality. It passed an 18psi pressure check. Anodizing was perfect. You may have to drill holes in the fuel rail stand if you use common aftermarket injectors to lower the rail height, not too big of a deal, it’s like 16ga aluminum sheet metal. I wouldn’t recommend this intake on naturally aspirated engines. TECHNICALLY it is a square port intake. It is a square port runner all the way down to the injector boss, which then flares out to a cathedral port (like a typical cathedral intake) but the difference is the runner is still square, the injector boss is totally separated from the runner itself and not blended into the runner. I’ve attached a picture for you to see. Running a square port intake on a cathedral head on an n/a engine will obviously work, but with significantly decreased power. Overall an 8/10. When you look at other high ram intake options, the prices are ridiculous. Would other intakes flow a little better? Yes. Would I run this over my Holley high ram on my drag truck? No shot. Did I put this on my turbo LS daily? Absolutely.

### ⭐⭐⭐⭐⭐ Nice aftermarket option
*by R***E on April 2, 2026*

Nice quality

### ⭐⭐⭐⭐ Not fit for c5
*by H***R on September 2, 2025*

Do not buy for c5 corvette Overall the intake looks great, quality is good as far as I can tell, I test fit one injector and it seemed to be good. There’s nothing I can say bad about the intake manifold itself But this is NOT made to fit a c5 corvette. You will have to cut your cowl to make it fit properly, if your not ready to cut your cowl, then do not buy this intake
