2.5in. Collector-4-2-1 Tri-Y Design-Pair With S2 Test-Pipe P/N 414-05-0070 for Optimal Results-Works w/OEM Catalyst. Skunk2 is proud to announce its all-new Alpha Series Header for Honda S2000s. Skunk2's Alpha Series Header for the S2000 was designed with the ease of installation and maximizing horsepower gains in mind. Skunk2 Engineers took advantage of the decision to make an Alpha Series Header, and as a result have designed a header that produces more horsepower and directly fits any forced induction applications. Our decision to produce the Alpha Series Header was driven by our desire to make our race-proven design more affordable and accessible to everyday enthusiasts. New manufacturing techniques allow us to do so at a lower overall cost, making race-winning header technology available to everyone. Skunk2's Alpha Series Header for S2000s offers Skunk2 performance, industry-leading customer service, and a full warranty policy, all at a price comparable to lesser budget-minded headers. Unlike the budget-minded headers, though, only Skunk2 Alpha Series Headers ensure precise fitment and the peace of mind of knowing that a Skunk2 representative is just a phone call or email away. All Skunk2 Alpha headers are designed and engineered to maximize exhaust flow and increase both horsepower and torque throughout the powerband. The unique design is the result of more than a decade of racing experience coupled with computerized modeling and extensive dyno testing. Each Skunk2 Alpha Series Header features equal-length, sequentially paired, stepped primaries in a 4-2-1 tri-Y design that terminates with True Merged Collector with a 2.5-inch outlet. Skunk2's Alpha Header also include 02 bungs for OEM and aftermarket sensors. Each header is constructed from stainless steel with mandrel-bent tubing for strength, corrosion resistance, and durability. The Skunk2 Alpha D-Series header also includes a donut gasket and a weld on exhaust flange, this included flange can be utilized as an option to weld the Alpha Header to an aftermarket exhaust. These features, paired with Skunk2's unique design specs, provide an extremely broad powerband that's applicable to a wide range of engine sizes and configurations. Alpha Series Headers also feature specific sized primary tubes to achieve optimum overall and peak power. By sizing the primary tubes diameter, Skunk2 is able to maintain the highest possible exhaust gas speed throughout the header, which improves mid-range power and throttle response significantly. Skunk2's Alpha Series Header provides the perfect combination of top-end power without sacrificing mid-range performance or throttle response. The Alpha Header will pair up perfectly with the Kraftwerks D-Series Supercharger Kit., and has all the clearance needed for a great fit.

Good fit, good construction.
Style: CA12289
This filter was a good fit for my Corolla. It appears to be well made. The gasket is resilient and looks like it would seal well, preventing any leakage past the filter. Construction was good, with no holes or gaps in the filter paper itself. Unfortunately, the buyer usually has no way to judge the performance of an air filter, and I'm no exception, so I can't say how effective it is in actually removing dirt from the air going into the engine. But I would buy this filter again.

Easy to install and great quality—perfect for my 2018 Civic
Size: 2.0L
I bought this for my 2018 Honda Civic, and it fits perfectly. It only takes a few minutes to install with just a few clips, and the process is simple. I am a woman and do it myself with no issues at all. The filter feels sturdy and well made. The thickness and overall quality are excellent. I’ve seen people mention “ease of cleaning,” but I don’t clean mine. I just remove, vacuum the area and replace it when needed. That might be a bit much, but it’s affordable and straightforward. I can’t say exactly how much it improves airflow or fuel mileage, but I consistently get over 40 miles per gallon in economy mode, so it’s clearly performing well. Overall, it’s a great product if you like handling basic car maintenance on your own.
