The Skunk2 Pro Series and Ultra Series are the clearest intake-manifold options in this list for Honda B-series VTEC builds. The Pro Series suits buyers comparing a manifold for naturally aspirated or turbocharged use; the Ultra Series is a candidate for buyers seeking larger-volume configurations. Check engine and vehicle fitment before ordering: some supplied listings describe other engine families or give conflicting compatibility details.
| Product | Best suited for | Key detail |
|---|---|---|
| Skunk2 Pro Series Black | B-series VTEC builds | 64 mm throttle-body opening, port-matchable up to 75 mm |
| Skunk2 Ultra Series Black Anodized | Buyers comparing manifold volume options | Listed in 3.5, 4.5, and 5.5-liter configurations |
| WENJTP Black Aluminum | Buyers verifying a possible B-series application | Listing title says B-series; features describe different vehicles |
| Skunk2 Ultra-Series Race Primary Fuel Rail | Buyers seeking a fuel rail, not a manifold | 6061-T6 aluminum; fuel-system component |
| WENJTP SOHC D-Series Manifold | D-series owners only | Not a B-series manifold |
Skunk2 Pro Series Black Intake Manifold
This is the most directly specified B-series manifold in the list. The listing describes it for Honda B-series VTEC engines and says its airflow design is intended to increase horsepower. Its stated applications include both turbocharged and naturally aspirated setups.
Best for: B-series VTEC owners comparing a manifold for either forced-induction or naturally aspirated use. The 64 mm throttle-body opening can be port-matched up to 75 mm, according to the product details.
Limitation: Port matching is not the same as confirming your throttle body or engine setup will fit. Verify dimensions and application before purchase.
Skunk2 Ultra Series Black Anodized Manifold
The listing identifies this as an intake manifold for Honda B-series 3.5L VTEC engines and notes 3.5-liter, 4.5-liter, and 5.5-liter configurations. It also lists high-grade mounting hardware and 6.5-inch tilted, tapered high-velocity runners.
Best for: B-series VTEC buyers who want to compare manifold-volume configurations and runner design. Check the exact configuration and engine fitment for the item being considered.
Limitation: The supplied details do not explain how each volume configuration affects a specific build, so match the chosen version to your engine and setup rather than assuming all options are interchangeable.
WENJTP Black Aluminum Intake Manifold
The product title describes a manifold compatible with Honda B-series VTEC engines, but its feature text instead names Honda Civic Si models from 2006–2011 and Honda TSX models from 2004–2008. It also specifies CNC 6061-T6 aluminum, a 70 mm throttle body, and a tapered plenum intended to support airflow.
Best for: Buyers willing to confirm fitment directly against the exact engine and vehicle before choosing this listing. The stated material and throttle-body size are useful comparison details.
Limitation: The title and fitment details conflict. Do not assume it fits a B-series engine without reliable confirmation for your specific application.
Skunk2 Ultra-Series Race Primary Fuel Rail
This listing is a primary fuel rail for Honda B-series engines, not an intake manifold. Its supplied details specify 6061-T6 aluminum construction, E85 and methanol compatibility, and support for up to 1,200 horsepower.
Best for: B-series owners researching a related fuel-system component alongside an intake-manifold purchase. It is included as a clearly labeled related part, not as a substitute manifold.
Limitation: A fuel rail does not provide the intake runners or plenum of a manifold. Confirm fuel-system requirements and fitment separately.
WENJTP SOHC D-Series Intake Manifold
This WENJTP manifold is listed for Honda SOHC D-series applications, including certain Civic, CRX, and Del Sol models from 1988–2000. The feature text describes a tapered design and larger plenum and runners intended for D-series engines.
Best for: D-series owners comparing an aluminum manifold for the listed engine family.
Limitation: This is not identified as a B-series part. B-series shoppers should avoid choosing it unless fitment is independently confirmed; the listing specifically describes D-series applications.
Buying Guide: How To Choose A B-Series Intake Manifold
Does the manifold match your engine?
Start with the engine family and VTEC configuration, then confirm the vehicle and year if the seller provides them. “Honda Civic” alone is not enough to establish compatibility because Civic models use different engines. Be especially cautious when a listing title and its feature text name different applications.
What throttle-body opening do you need?
Compare the manifold opening with your throttle body and planned setup. The Skunk2 Pro Series listing gives a 64 mm opening and says it can be port-matched up to 75 mm. The WENJTP listing states a 70 mm throttle body but has conflicting fitment information. Do not treat those dimensions as proof of vehicle compatibility.
Should you choose a Pro or Ultra Series option?
The Pro Series listing explicitly mentions naturally aspirated and turbocharged applications. The Ultra Series listing emphasizes its available volume configurations and tapered runners. The supplied details do not provide a direct performance comparison, so use verified engine fitment, dimensions, and build requirements to choose between them.
What else should you verify?
- Confirm the exact engine code and manifold bolt pattern.
- Check throttle-body, fuel-rail, and accessory clearance for your setup.
- Verify whether mounting hardware is included; the Ultra Series listing specifically mentions hardware.
- Keep fuel rails separate from intake manifolds when comparing parts.
Frequently Asked Questions
Which product in this list is explicitly for B-series VTEC engines?
The Skunk2 Pro Series listing explicitly identifies Honda B-series VTEC engines. The Skunk2 Ultra Series listing also describes a Honda B-series VTEC application, but buyers should verify the exact configuration.
Is the Skunk2 primary fuel rail an intake manifold?
No. It is a fuel rail, a separate fuel-system component, and cannot replace an intake manifold.
Does the WENJTP black manifold definitely fit a B-series engine?
The supplied information does not establish that clearly. Its title says B-series, while its feature text names different vehicles and model years. Confirm fitment before purchase.
Can a D-series manifold be used on a B-series engine?
The supplied listing identifies the WENJTP manifold as a SOHC D-series part, not a B-series part. Do not assume cross-fitment without specific confirmation.
What should I check before ordering?
Verify engine family, VTEC configuration, vehicle application, throttle-body dimensions, and any required hardware against the exact part listing and your build.
