This is a replacement air filter housing that has not been drilled for the secondary air system (SLS) tubes. If for some reason you should decide to remove the SLS tubes which run from the air filter housing to the cylinder heads, then you will have a couple of holes in the housing. These holes can be plugged of course and the timing plugs work great for that. If however you want the cleanest appearance possible, then you can replace the lower housing with this part.
We imported a number of these housings from Europe. They were used but in good shape. They have been stripped to bare aluminum and powder coated 60% gloss black, which matches the original finish perfectly. The part looks like brand new! And for all practical purposes, it is.
If you install this part, it's also the perfect time to replace your fuel hose and run the crossover hose beneath this housing as it was intended, then install fuel line T fittings. By doing so, you will have much less lag time when you hit reserve and that is a huge safety benefit, especially in traffic.
For the best results, you will also want to replace your starter cover. Have a look that the Related Products for more information about that and other items.
