This is the heart of the most popular air-cooled stroker there is. EMPI's 94mm x 82mm piston and cylinder set (98-1957-B) is the matched four-cylinder kit that builds a 2276cc Type 1 when you run it on an 82mm stroker crank. Big bore, big stroke, one matched set — pistons, cylinders, rings, pins and clips.

Features

  • 94mm bore x 82mm stroke — builds 2276cc, the go-to air-cooled stroker displacement
  • Matched set of 4 — pistons and cylinders sized together
  • Includes rings, wrist pins and clips — a complete top-end set
  • Designed to pair with the EMPI 82mm counterweighted crank (00-8182-0)
  • Requires case and head machining for the 94mm bore (see Fitment)

Fitment

This is a build component, not a bolt-in. A 94mm bore requires the case cylinder spigots and the heads to be machined to accept 94mm barrels, and the 82mm stroke requires case clearancing. Built for Type 1 cases going to 2276cc with a matching 82mm crank. CONFIRMED: Type 1 cases machined for 94mm x 82mm. NOT CONFIRMED: stock un-machined cases, Type 4 engines.

Easy
Size: CF11966&CA12166
Perfect fit. Easy to install. Good price. When changing the cabin filter the screw removal is a little easier if you notch out the plastic in front of it. Its behind the glove box and is not noticeable.

Excellent Air filter - Easy installation.
Style: BE-743 1-Pack
Excellent AC and Heater Cabinet odor defense air filter. I noticed immediately the smell coming out of the vents was fresher and the musty smell that was coming from the vents was crisper and cleaner. Very easy installation that you can do yourself and don’t need to pay a shop to do. The price is one of the best online and coms in quickly. It’s very sturdy, filter quality is excellent and it definitely improves the air quality and flow in your car. Fits perfectly like any OEM filter, this is a great buy for the price of an installation that will take you Les then 10 minutes to do yourself.

Great filter and easy installation
Style: BE-159 1-Pack, Style: BE-159 1-Pack
For my 2016 Hyundai Sonata Hybrid Limited. I cannot believe I paid so much more for a brand-name filter that does the same thing as this one. It is made of the same material as the dealer one I took out. Very easy to install, cant believe I paid for this to be done in the past with oil changes. Requires no tools and did not get dirty at all. No mechanical skills needed, especially if you run into trouble and can use YouTube. PROS - great quality, cannot tell that it is after-market - very professionally made, not irregularities seen - excellent fit in position, no adjustment needed - very easy to install, cannot believe I paid to have this done in the past - no mechanical skills needed to install - great price compared to what big name productions want for the same thing - cannot tell the difference in air quality between this and the dealer filter I took out - removes outside odor completely - did not require tools are getting dirty CONS - None
