pA European Emblems & Badges Re-badge your XR4 with Ford ovals
and Sierra emblems or put the finishing touches on that Cosworth clone.
Genuine Ford European logos will distinguish your XR4 or Scorpio from the
rest. Location (on car) for emblems and sticker logos are listed below.
Emblems are chrome and black plastic with self stick backing. Stickers can be
applied to metal or glass surfaces.

European Headlamps The standard US spec. XR4 & Scorpio
headlights were pretty poor when new, and get worse with age- especially when
the lenses turn cloudy. European headlamps will provide a significant increase
in light output and they look great too. These lamps utilize all glass lensing with
a halogen H-4 55/60 watt bulb for high/low main beam operation, and a halogen
H-3 55 watt bulb for the built-in driving lamp.
Note: Lamps are supplied in right hand
drive (English) specification which has a subtle different low beam flair pattern,
however, this is not very noticeable. If required left hand (German) type lenses are
available separately (see price list). We recommend installing the lamps first before
opting to swap out the lenses as most customers do not bother.

Head Lamp Bulbs Replacement and higher wattage bulbs for above
European headlamps and standard XR4 & Scorpio aerolamps. Headlamps- H4
bulbs are fit eurolamps (not stock headlamps), 9004 bulbs are for use with standard
XR4Ti & Scorpio aerolamps. Fog lamps- H3 bulbs are suitable for eurolamps and
Scorpio, 880 bulbs fit
only XR4Ti fogs. Krypton gas 9004 "Bright White" bulbs burn
brighter with more luminous output than standard halogen type bulbs.
"Blue Ion"
bulbs project a, low glare, blue tinted beam- definitely a different look !

Rear Tail Lamp Seals & Lamp Sockets Puddles in the trunk or damp
carpeting might be due to leaking rear tail lamp seals. Non-functioning tail
lamps are usually due to corroded lamp sockets. We have new replacements
for both these USA Ford unavailable parts.

The cooling system on the XR4Ti is fairly unique. If there is
another car with more individual hoses in the cooling system,
we have yet to see it. Compound this with the changes
throughout the model run and it gets even more complex. We
have a good inventory of the hoses and other cooling related
components that fit 1985-87 XR4Ti and some (where similar
or noted) for 88-1989 cars.

Cooling System (Scorpio)
In addition to our stock of cooling system components for the XR4Ti
we have added the various Scorpio related items to our inventory.
The Scorpio's cooling system is only slightly less complicated than
the XR4Ti's, it's only saving grace is the parts do not vary all that
much from year to year. Again, as with the XR4, components that
we offer are from the O.E. supplier or Ford originals.
