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. Review: Not fit for c5 - 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 ## Features - 💨[Engine] Intake manifold for LS based engines with cathedral port heads shape, 6.0L 5.7L 5.3L 4.8L LR4,L33,L59,LM4,LM7,LS1,LS6,LQ4,LQ9, LS2. - 💨[Model] LS intake manifold is compatible with Chevy Corvette 97-04, Pontiac Firebird Formula, Trans AM 98-02, Corvette Z06 01-04, Cadillac CTS V-series 04-05, Chevrolet Corvette 05-07,Chevrolet SSR 05-06, Chevrolet TrailBlazer SS 06-09, Cadillac CTS V-Series 06-07, Pontiac GTO 05-06, Saab 9-7X Aero 08-09 - 💨[High Strength] Made of 3mm thickness T6061 sheet aluminum; TIG welded; hold up to 30lbs.The intake will not bend or flex with boost or vacuum bore. - 💨[Function] Reduce air flow resistance, increase air flow, and distribute air flow to 8 cylinders more evenly, thereby improving performance and throttle response. - 💨[Package Includes] Intake manifold with rear map sensor port, gaskets, hardware, fuel rails, fuel crossover line.(92mm throttle body, throttle position sensor (TPS),Injector are not included.) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09FJF11YK | | Best Sellers Rank | #330,340 in Automotive ( See Top 100 in Automotive ) #263 in Automotive Replacement Engine Intake Manifolds | | Brand | POSENG | | Customer Reviews | 3.9 3.9 out of 5 stars (91) | | Date First Available | September 6, 2021 | | Item Weight | 16.81 pounds | | Manufacturer | POSENG | | Manufacturer Part Number | IM-1011-S-CS | | Package Dimensions | 23.2 x 13.9 x 9.9 inches | ## Images ![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 (Silver 92MM) - Image 1](https://m.media-amazon.com/images/I/71fMZ3tkulL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 8/10 for a boosted engine. *by W***N on June 23, 2025* Intake looks fairly good quality.
