Stage 2 Bundle
One-Click Horsepower: Curated Stage 2
Bundles for the Jeep Grand Cherokee
Hand-picked by FastHemis for every Grand Cherokee generation and engine — 2005–2010 WK (5.7L Hemi, 6.1L SRT8), 2011–2021 WK2 (3.6L V6, 5.7L Hemi, 6.4L SRT / SRT8), and 2022–2026 WL (3.6L V6, 5.7L Hemi). Each bundle combines an aFe cold air intake, Ripp high-performance coil packs, E3 spark plugs, a performance exhaust system, and a throttle body upgrade for bolt-on gains up to +95 HP — no tune required.
Important
What to Know Before You Buy
What Is a Stage 2 Bundle?
Everything in Stage 1 (cold air intake, high-performance coils, spark plugs) plus a cat-back exhaust system and throttle body upgrade. Five components working together for maximum bolt-on gains — no tune required, safe for stock PCM. Stage 2 adds exhaust flow and throttle response on top of the airflow and ignition improvements from Stage 1.
Why Buy the Bundle?
Each Stage 2 bundle is hand-picked by FastHemis specialists for your exact Grand Cherokee generation and engine (WK, WK2, or WL). All five components are confirmed compatible, tested together, and priced better than buying individually. One click, one shipment — no sourcing five different products, no guesswork on fitment or compatibility.
Installation
DIY-friendly, 3–5 hours total. Intake, coils, and plugs: ~2 hours. Throttle body: ~30 minutes (BBK 78mm Pentastar units may call for a short pedal relearn per instructions). Cat-back: ~1–2 hours — a lift or tall jack stands help on an SUV. Basic hand tools, no wiring, no tuning. E3 plugs come pre-gapped.
Warranty & Emissions
aFe intakes are 50-state legal where applicable. Ripp V6 coil packs carry CARB certification (EO: D-705-2). E3 plugs and Ripp HEMI coils are emissions-neutral with appropriate plugs. Exhaust systems and some throttle bodies may be restricted for street use in certain states — check local regulations. Bolt-ons do not void your factory warranty under the Magnuson-Moss Warranty Act unless they cause a related failure.

The Scoop
Why this bundle? The WK 5.7L Grand Cherokee is a classic daily and tow rig that responds well to breathing and ignition upgrades. This Stage 2 kit delivers +79 HP combined: Magnum FORCE Stage-2 (51-10242), Ripp MV8-CPK coils, E3.66 plugs, MBRP Installer cat-back (S5508AL), and aFe 90mm throttle body (46-39112). You get cooler, denser air in, a stronger spark and burn, less restrictive exhaust out, and a throttle plate sized for the new airflow — all without opening the PCM.
What’s included? aFe Magnum FORCE Stage-2 Cold Air Intake (51-10242, Pro DRY S), Ripp HEMI High Performance Coil Packs (MV8-CPK, 8-pack), E3 Spark Plugs (E3.66, 8 included), MBRP Installer Series Cat-Back Exhaust System (S5508AL), and aFe 90mm Throttle Body Kit (46-39112). Confirmed for 2005–2010 Jeep Grand Cherokee 5.7L Hemi.
Will the MBRP system use my factory hangers? Yes. The Installer Series cat-back is designed as a direct replacement from the converters back, using OEM-style hanger locations on the WK platform so you are not fabricating mounts — plan for typical SUV clearance and rust-penetrant on older hardware.
The MBRP Installer Series cat-back (S5508AL) is the halo piece in this WK Stage 2 bundle: 3-inch mandrel-bent aluminized tubing, Street Profile tuning, and a polished single exit that looks right on an older Grand Cherokee. It replaces the restrictive factory routing from the cats rearward so the 5.7L can exhale what the intake, coils, plugs, and 90mm throttle body help it ingest.
Together, the five parts close the loop on bolt-on performance for 2005–2010 5.7L WK SUVs — +79 HP combined in one curated shipment, with install times realistic for a driveway or shop day.

You get aFe Magnum FORCE (54-11192) for cooler air, Ripp MV8-CPK coils and E3.66 plugs for authoritative ignition, CORSA Sport cat-back (14451) for a purposeful exhaust note and flow, and aFe 90mm (46-39112) to remove the throttle bottleneck. It is a curated “whole engine breathing” package for the original super-SUV.
What’s included? aFe Magnum FORCE Stage-2 Cold Air Intake (54-11192, Pro 5R), Ripp HEMI High Performance Coil Packs (MV8-CPK, 8-pack), E3 Spark Plugs (E3.66, 8 included), CORSA Sport Cat-Back Exhaust Polished Tips (14451, rear section), and aFe 90mm Throttle Body Kit (46-39112).

How does the CORSA system sound on the SRT8? CORSA’s Sport calibration delivers a noticeable performance tone when you dig into the throttle while using RSC technology to limit droning during steady cruise — ideal for an SRT8 that still sees street miles.
The CORSA Sport cat-back (14451) is the standout in this SRT8 Stage 2 kit: polished tips, Sport-level volume, and engineering focused on flow and drone control. It replaces the factory rear exhaust section with a stainless path that lets the 6.1L exhale after the aFe intake and 90mm throttle body move more air in.
With Ripp coils and E3 plugs ensuring the chamber lights cleanly, this five-part bundle is our hand-picked stack for WK SRT8 owners who want bolt-on gains without PCM tuning — +78 HP combined as listed for this FastHemis Stage 2 product.

The Scoop
Why this bundle? The WL Grand Cherokee 3.6L is the volume engine for the current generation — this Stage 2 bundle stacks +70 HP with Momentum GT (50-70107D), Ripp 1819JLCPK-WK coils, E3.82 plugs, Borla S-Type cat-back (140955), and BBK 78mm (1841). You get premium intake, ignition, a Borla True Dual exhaust with X-pipe, and a larger throttle body in one checkout.
What’s included? AFE Momentum GT Cold Air Intake (50-70107D), Ripp Performance Coil Packs (1819JLCPK-WK, 6-pack), E3 Spark Plugs (E3.82, 6 included), Borla S-Type Cat-Back Exhaust (140955), and BBK Performance 78MM Throttle Body (1841). Confirmed for 2022–2026 Jeep Grand Cherokee 3.6L V6 per the bundle product page.
Why does Borla list different trim notes on the raw product copy? Always defer to the FastHemis bundle product page and Borla box label for final WL 3.6L fitment — this kit is curated so the exhaust, intake, coils, plugs, and BBK throttle body ship as one matched Stage 2 order.
The Borla S-Type cat-back (140955) is the halo upgrade for WL Pentastar Stage 2: True Dual layout, Merge X-Pipe, T-304 stainless, and tailpipes sized to work with the factory valance tips so the rear of a new Grand Cherokee still looks OEM-fresh while flowing more exhaust. It is the sound and flow centerpiece after the Momentum GT and BBK throttle body increase air in.
Ripp WK-specific coils and E3.82 plugs keep combustion honest — +70 HP combined for 2022–2026 3.6L owners who want a complete bolt-on stack without piecing five vendors together.

Common Questions
Frequently Asked Questions
Do I need a tune for the Stage 2 bundle?
No. All five components in each Grand Cherokee Stage 2 bundle are selected to work with the stock PCM. No tuning, no flashing, no ECU modifications. BBK 78mm throttle bodies on Pentastar bundles may use a short pedal relearn per BBK instructions; aFe 90mm HEMI throttle bodies are plug-and-play with no tune per aFe for typical bolt-on use.
Will the Stage 2 bundle void my factory warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your entire warranty for aftermarket parts alone. aFe intakes are 50-state legal where applicable; Ripp V6 coils carry CARB EO D-705-2. Exhaust and some performance parts may be restricted for street use in certain states — verify local law. Keep your stock components if you need to revert for service.
Why buy the Stage 2 bundle instead of parts individually?
The bundle is priced lower than buying each component separately, ships in one order, and every part is confirmed compatible with your Grand Cherokee generation and engine. No sourcing five SKUs from multiple vendors or second-guessing cat-back vs intake pairing across WK, WK2, and WL platforms.
Can I install this myself?
Yes. Expect 3–5 hours total: intake, coils, and plugs (~2 hours), throttle body (~30 minutes), cat-back (~1–2 hours). A lift or tall jack stands make SUV exhaust work much easier. No wiring and no tuning for the HEMI 90mm path; follow BBK instructions for V6 pedal relearn if required.
What’s the difference between Stage 1 and Stage 2?
Stage 1 is intake, coils, and plugs. Stage 2 adds a performance cat-back and throttle body for higher combined gains — from +70 HP on WL 3.6L up to +95 HP on WK2 6.4L SRT / SRT8 in these listings.
What comes after Stage 2?
Headers, high-flow mids, custom tuning, camshaft upgrades, or forced induction. Your Stage 2 foundation supports those steps — Ripp coils are boost-friendly, and the 90mm throttle body pairs well with future blower kits on HEMI applications.
