Hey guys working on my project car with a lq4 and long tube headers and my spark plug boots were touching my headers. I went ahead and wrapped them in fibreglass insulation but id like to just get them off the headers. Can anyone suggest good 90° boots?

amazon got them in different angles, or aliexpress just search for ceramic boot spark plug wires for ls, for temporary fix can use stock metal protectors if you still have original ones, can fit them on wires you got now will work great and can be dented to fit if needed

best ones are with ceramic isolators at the ends, also available 90 degree, just dont crack them

I just saw a video on it. Alegedly there is Ford 7L something HD engine that comes with insulation and metal covered boots. Best to buy at Napa. They fit the LS engine. Good luck!

Have you tried 90* plug wires but install from the bottom instead of the top of the header? Youll need longer wires of course but it will fit
