25 Row (13" x 1 1/4" x 7 1/2") -- Recommended for more intense applications where occasional track use will be seen, also for more moderate climates.

34 Row (13" x 1 1/4" x 10 1/4") -- Recommended for forced induction applications, serious track use, or in high temperature climates where more cooling is required. Our most popular core, even though it is our largest standard offer core it still fits great even with Stillen Gen 3 intakes.


wouldn't 19 row be enough? Theres no tracks around where I live haha
