High-Performance LSX Pistons on a Budget
Mahle Motorsport // 800.223.9152 // http://www.us.mahle.com/en/
The words budget and forged internals don’t always belong in the same sentence, but the PowerPak line of pistons from Mahle provides the strength and reliability you need in high-performance environments for the budget-minded consumer running an LS-based engine. These pistons, forged from 2618 aluminum, have increased detonation resistance and feature a valve-pocket design that makes them compatible with LS1, LS3, and LS7 cylinder heads. Other configurations include flat, dome, and dished tops, bore options from 4.000 to 4.185 inches, and compression ratios from 10:1 to 14:1. A performance ring pack is also included, comprised of 1.0mm top, napier 1.0mm 2nd, and 2.0mm HV358 coated steel oil rings. The skirts are treated with Mahle’s proprietary Grafal coating to reduce wear, drag, scuffing, and friction while the pin bores and ring grooves are covered in a phosphate coating.
Price: $764.55 for piston and ring kits (from Summit Racing)

Let Your Gen 3 LS Breathe Easy With a New Intake
Holley // 866.464.6553 // www.holley.com/
Holley has released the Single-Plane Split-Design EFI Race Intake Manifolds for GM Gen 3 LS engines. They’re perfect for race and high-performance LS engines and are designed specifically for cathedral-port cylinder heads and 4150-style square-bore throttle-bodies. They’re lighter than ordinary split intakes and cost much less. The two-piece configuration makes them easy to disassemble for custom porting, and shoulder-bolt locators and captured O-rings make reassembly simple and precise. These manifolds are available in silver and black, and the height of 7.32 inches allows for plenty of underhood clearance. They’re ideal for EFI applications with displacements from 5.3L to 6.2L and deliver optimal performance across your entire rpm range and maximum power up to 7,000 rpm. To ensure a fast, hassle-free installation, the fuel rails, O-rings, and all the necessary fasteners are included.
