I had somebody try to tell me that there's a new manufacturer of CV
boots out there that uses thicker rubber than Honda OEM. Unfortunately
I don't remember the name of the maker. Anyone heard of this?

er, so what exactly does "thickness" have to do with rubber selection,
rubber quality or component design? i've yet to see an instance where
oem componentry quality did not exceed that of after-market for honda.
you can therefore be confident that oem is the way to go. ford otoh...

Honda fits only short branch ( 4 into 1 pipe ), cheap & heavy cast iron
exhaust*manifold for its engines <2.2 litre, even a F22A's *'s twin pipes
are short. Result is lower though adequate torque @ low rpm ( as during
buyers' test drives ), but very low ( <½ as much ) torque & mpg @ high
( >3000 ) rpm, this difference rises with rpm.

My local-made 4-2-1 * [i] uses aluminised mild steel [ii] is 13 kg <
original * [iii] has longer twin pipes than a F22A's * [iv] twin pipes'
interiors' total cross section area is 60% > original * ( single pipe )'s.
In 6-02 I saw a new Civic vtec 1.6 litre engine with very short * : a waste
of vtec ( no way is torque / mpg esp @ high rpm maximised ).
www.turborick.com/gsxr1127/gasoline.html para 10.2(1) indicates how
bad a civic's * is. Many car makers ( incl Nissan in Sunny 130Y, Hyundai
in Sonata 2.4, Proton in Waja 1.8 ) save on *, because 99.99% buyers
don't test drive on highways, or know / experienced a difference between
short & long branch *.

My F20A had crude carbon-core cables made by Sumitomo, efficiency
was low ( even by 1990 std ) : longest cable has 12.7k ohm
www.magnecor.com/magnecor1/truth.htm I've changed my F20A's plug
cables 4x, present set ( German cables ) has just 0.2 ohm/ ft : when
warm & w/o load, my F20A can idle @ just 600 rpm, with load then
550 rpm ( without shaking / stalling ). Plug gaps are 2mm. All these are
impossible with crude carbon-core cables. How low can your original
spec engine ( with crude carbon-core cables ) likewise idle @ ?
Carbon can absorb RFI, but cannot conduct as well as metal : high
efficiency cables makers coil metal wires around carbon cores, then use
these coiled wires to conduct : spark size Ø expands from ½ to 3 mm,
10x brighter, colour turns fr deep blue to bright yellow, 5x as loud.( in
open air ).
@ high rpm, any engine with 1 small coil & crude carbon-core cables
will have very small sparks, low torque & loud exhaust noise. This
inadequacy is esp bad in a 2 litre SM4 accord ; combined gear ratio
3.1323 is > those of 2 litre Toyota / Nissan models, e.g. 9.78% >
Nissan Cefiro' s 2.8530 : 75 mph requires 3341.7rpm, but a Cefiro
requires just 3043.7 rpm, on the same 205/65R15 tyres.
