The factory intercooler on the SR20DET in the S13 Silvia and 180SX is one of the first restrictions that appears as soon as boost levels rise or supporting modifications are added. The GReddy Intercooler Kit Spec LS (12020479) is a smart, lightweight upgrade that brings meaningful cooling improvements without the high cost of premium models. With a 600 x 284 x 66mm core and high-quality 2-ply silicon hosing, this intercooler dramatically lowers intake air temperatures, allowing for safer boost levels and stronger, more consistent power delivery across the RPM range.
As the successor to the popular Spec M, the Spec LS maintains excellent cooling efficiency while reducing overall weight for better front-end balance and sharper handling. The kit is engineered for straightforward installation on S13 chassis, including all necessary components for a clean, professional fit. This makes it an ideal choice for street-driven cars, drift builds, or track machines where budget and practicality matter as much as performance. The result is noticeable gains in throttle response, reduced heat soak, and improved turbo efficiency without compromising reliability.
At Terra Firma Automotive, we supply this genuine GReddy Intercooler Kit Spec LS as a premium yet accessible cooling upgrade for S13 Silvia and 180SX owners. It strikes the perfect balance between performance, weight savings, and value, helping your SR20DET run cooler and stronger under boost. For enthusiasts looking to take their RWD SR20-powered car to the next level without overspending, this Spec LS kit is one of the most practical and effective upgrades available.
