Opinions on header wrap for svt header?
Going to be installing my svt header soon and wanted to order the header wrap for it... Obviously lots of guys on here have done this swap... I remember seeing a post with amount of header wrap someone used but can't seem to find it now... So wondering what everyone has used(dei titanium, regular wrap with silicone coating, ect)? Also what size roll(I.e. 2in x 50ft roll, ect)? And feedback would be greatly appreciated... Thanks...

2" x 50' will be just enough to wrap the whole header. What brand you use is up to you. I would suggest though spraying it with some of that header wrap spray that they make to help it keep from rotting off. I just used some generic header wrap off of Ebay and it worked fine, it is after just fiberglass or what ever it's made of, though I've header good things about that titanium DEI wrap, but to me it's all the same.

Thanks... I thought I had read a thread when doing previos searches that a 50' roll would work... Wasn't sure if it was one or two inch tho...did u coat yours afterwards with the silicone spray? Or while u were wrapping it? Also how many ties did u use and what size? And how much a overlap did u use when wrapping?

I used a inch over lap on the 2" wide roll, I forget how many ties I used but I remember it was quite a bit more than I thought it would be, but I also wrapped each pipe separately where some will wrap a pipe and move onto the next one. I didn't spray it with anything and it eventually rooted and fell off. If you touched it, it would turn to almost dust lol but I had mine on for a long time, it all falls off and rots eventually. It drastically lowered my under hood temps though when it was on there. You could put your hand on the intake side of the valve cover and hold it there, before you couldn't do that.

Thanks for the info... I kno this is proly a stupid ? But do u remember if it was dei wrap or the no name stuff? Also how long did it last? Proly gonna be about a year if I do go FI but I plan on keeping the car a long time...

Doesn't matter what brand it will all rot eventually. A local member has the DEI stuff and it's rotting off too. The stuff I used was the no name ebay stuff. It should easily last a year though. Mine lasted a few years without being sprayed.

I used aircraft wire to hold mine in place.
The last one I wrapped I used the ties in the kit and cut the hell out of my fingers. Never again I told myself.

And, thicker doesn't change anything. It's how tight the wrap is that makes it work well.
I've done minimal overlap, double wrap and in-between. Surface temp didn't change much at all.
The biggest change I saw was wrap with the factory heatshield.

Ok thanks... I appreciate the info from both of you... I think I will just buy dei wrap and hope for the best.. It's not a huge difference in price... Iminhell... Will I need the svt heat sheild or will my stock zetec one fit? My stock one is in almost perfect shape...

It's spendy but helps tremendously.
Use large flat washers on both sides of the lower mount bolts. That point gets very hot and it's the fist place mine rusted through, in like 6 months.

Ok Ile look for a sheild on here... Thanks
