The LSXRT High HP Runner intake manifold built by Fuel Air Spark Technology (FAST) was previously only available for LS1, LS2, and LS6 applications. Recently, FAST launched an iteration for those who are utilizing the 6.2L LS3 V8.
FAST states that this manifold is best suited for high-revving race engines, with peak gains of 30 horsepower. Based on the LSXR manifold, this version gives LS3 engines with rectangle-port cylinder heads even more plenum volume. You can see a list of the main features below:
- Proven high-rise design delivers gains of 30+ horsepower
- Feature larger plenum volume than LSXR High HP intake manifold
- Raised throttle body location to clear truck drive accessories
- Best suited to high-RPM race engines
- 50-state carb legal
Pricing on the LSXRT intake manifold for other applications is about $1,033 on FAST’s website, we expect pricing on the LS3 manifolds to reflect this number.
