Ok my K brace/bar bolts directly to the firewall at those 3 locations so no need for the extra support piece you show.

Ok, I see now, from the pic it looked like the reinforcement plate bolted to the same place as the K brace and hung out over the engine bay, but I see now that it sets under the cowl panel between the K brace and firewall on top of the wiper motor well.

So does it go on top of K brace at cowl or under it between cowl and K brace. Does it require complete removal of cowl cover to install?
Does it come with bolts for firewall attachment point or reuse existing bolts?

• Follow instructions that came with the Ford Performance Strut Tower Brace Kit or the instructions on AM to remove the useless plastic cowl brace.
• The cowl will be loose, but held on by the wiper arms. Remove the wiper arms.
• Install the cowl extension using the 3 new additional M8x29MM bolts. (same as 4 bolts already removed for the plastic cowl brace)
• Resume with the install of the K brace and strut tower brace.

Just checked and I do not have the firewall to cowl extension brace on my pony, so I guess a I can add another item to my wish list.

Isn't that always the case. Every time I read someone else's posts I fear that I will find another "must-have" item.

Sorry to necro this thread, but I didn't want to create a new one to ask a related question, when all the info could be here for future reference.

I'm getting ready to buy the FP strut tower brace kit for my '22 Eco Premium, but also intend to buy the cowl extension and wanted to make sure that I did not need to buy any more bolts than what I will already have once everything arrives.

I noticed a discussion here about a fifth boss on the cowl extension that one of the posters there evidently didn't have a bolt for, but from the discussion I couldn't tell if I will need a bolt for this or not on my '22.

The install seems relatively straightforward, as does KW's step-by-step above, but since I'm still a bit fuzzy on what I need for the cowl extension bracket, I thought I'd ask before getting elbow deep into the install and realizing that that one bolt I wasn't sure whether I needed has just become the most important thing that's missing in my life!

Thanks, all. Appreciate the help!

You need a total of 7 bolts to install the K brace and cowl extension part number W717964-S450B. The strut tower/k brace kit will come with 4 of those bolts I believe but the cowl brace does not come with the bolts so you will need to order 3 but I believe they come in packs of 4 from ford so you should have one left over.

If you have not already bought the cowl extension or not but there is a used one in very good condition on ebay for sale at about 15+ bucks below new, Ots not a part that will ever be seen so appearance is not an issue. Ot fits 15-23 models so do not let the 15-17 model year designation keep you from buying it. They had 2 for sale and I bought one of those 2 for my 2020.
