These headers are made exclusively for LOJ Conversions by renowned header manufacturer Kooks! You simply will not find a finer quality header anywhere! 


LOJ Conversions 350z / G35 LS Swap Headers are constructed of 100% USA Sourced T304 Aircraft Quality Stainless Steel, with mandrel bent 1.875” ID primaries and 3” collectors. The flanges are 3/8" thick laser cut stainless steel. The headers are TIG welded at the flanges, the inside of the ports are hand ground for maximum flow, and the flanges are machined flat after welding is complete.

The collectors feature full flow construction with internal scavenging spikes for maximum performance. The headers include new gaskets and bolts for attachment to your cylinder heads. These headers are custom made for the 350Z / G35 engine bay and are designed to fit perfectly when using the LOJ Conversions 350Z / G35 Engine Swap Kits!! Absolutely NO modifications to your car are required to fit these headers when using our swap kit!

ATTENTION 2006 350Z OWNERS! - The 2006 350Z has a different steering rack than all other years, the hard lines coming out of the rack interfere with one primary on the drivers side header. This is ONLY on 2006 model 350Z cars, Nissan added a speed sensitive variable assist PS system in 2006 that changed the rack design. They left the system in the 2007-2009 cars as well, but changed the rack again in 2007 and our headers work with this rack as well. If you want to run our headers you need to modify these lines or swap out the steering rack. You can delete the variable assist system by switching to a 2003-2005 rack, or keep the system and use a 2007+ rack. 

These headers carry a LIFETIME WARRANTY to the original purchaser covered by Kooks.

Testimonials

I was reminded this morning, two years after I bought my Z32 swap kit what a great company this is. LOJ is always there with excellent advice, not just great products. Best customer service of any company I’ve ever dealt with, and the highest quality swap parts available. If you want an easy, bolt in swap, this is it. Click Here to See Review
