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.

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 ## Frequently Bought Together - POSENG Intake Manifold for LS Cathedral Port Heads for LS1 LS2 LS6 LS Engines Compatible with Chevy 4.8 5.3 5.7 6.0 HTRACING (Black 92MM) - MUGE RACING 92mm Throttle Body Assembly with TPS IAC Throttle Position Sensor for Chevy LSX LS LS1 LS2 LS3 LS6 LS7 Black - 4-Bolt Throttle Cable Bracket Intakes 92MM-102MM Throttle Cable Bracket Replaces# 81012/81042 / 81001/81002 / 81003/81007 / 81043/81044 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/395874964-intake-manifold-for-ls-cathedral-port-heads-for-ls1-ls2](https://www.desertcart.co.th/products/395874964-intake-manifold-for-ls-cathedral-port-heads-for-ls1-ls2) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-27*
