The Blox Racing Tri-Y Headers are based off a really popular design and are designed to make power for your B-series engine. Blox offers two different headers, depending upon your engine size and estimated output. For B16A's or other 1.8L motors that are mildly built and have compression ratios 11:1 and less, we recommended the HiFlo Header. For bigger displacement B-series engines such as 2.0L or high compression 1.8L (11.5:1 and higher), we recommend the Max-Flo header. The difference between the headers is the size of the primaries inner diameter. Both headers make great power and on occasion, you can witness a 12hp increase over a DC JDM header, |
