		    ECHLIN SENDS LETTER TO SHAREHOLDERS

      BRANFORD, Conn., March 23, 1998-Echlin Inc. (NYSE:ECH) said today
that it has sent a letter from Larry McCurdy, Chairman, President and Chief
Executive Officer, to Echlin shareholders. The following is the full text
of that letter:



Dear Fellow Shareholders:

      By now you have probably been deluged with soliciting material from SPX
Corporation asking you to support SPX in its attempt to call a special meeting
of Echlin shareholders, remove the current Echlin Board and install a board
dominated by SPX management to approve SPX's proposed offer. SPX has made a
lot of claims in those materials that just do not stand up to scrutiny, and
we think that if you take the time to read this letter you'll agree.


Echlin's Repositioning Strategy Is Working And Is Delivering Value to Echlin
Shareholders

      Within the past year, under a new management, Echlin has instituted a
strategic repositioning plan that includes divestiture of underperforming or
non-strategic businesses, factory rationalizations, aggressive cost-cutting
aimed at profit improvements, heightened asset management and cash flows gains,
and a steadfast commitment to incorporating the Economic Value Added ("EVA")
framework.  In a recent conference call with industry analysts, SPX Chairman
and Chief Executive Officer, John Blystone, agreed that "the road map that
they've [the Company has] tried to lay out including the sale of one of their
businesses they announced this morning is fundamentally the right track."(*)
We believe that Mr. Blystone simply wants to seize credit for the results of
our action plan.

- ----------------------
(*)Permission has not been sought or received to quote from, or refer to,
published materials cited herein.

      Since the initiation of this plan in September 1997, seven non-core or
under performing businesses have been identified and either sold, or placed
under contract to be sold, resulting in proceeds to the Company of $281
million.  Fourteen facilities have been identified for closure and/or
rationalization as part of the plan.  Of the fourteen, four have been
completed, eight are currently being processed in accordance with the action
plans which have been established and the remaining two facilities are in the
final stages of completing their action plans for approval and implementation.
The results of this restructuring are clearly evident in our financial
performance. We have exceeded First Call consensus analyst earnings estimates
and have significantly improved our operating margins since the restructuring
was announced. All of this has been accomplished in the face of a very
difficult industry environment.

      Most importantly, our share price has gone up 27% in the twelve month
period prior to the announcement of SPX's proposed offer.

      SPX has also questioned the strength of Echlin's leadership team. Larry
McCurdy, who became Echlin Chairman and Chief Executive Officer in March 1997,
has over 20 years of high level managerial experience in the auto parts
businesses in which Echlin is engaged -- Mr. Blystone has virtually no
experience in these businesses.

Industry Analysts Have Expressed Doubts About Blystone's Synergistic Rationale
For An Echlin-SPX Combination

      SPX is fond of quoting industry analysts in its solicitation materials.
However, you should be aware that a number of industry analysts have expressed
doubts about the synergistic rationale for an Echlin-SPX combination:

	    * "Echlin and SPX operate in very different markets.  The
	    importance of long-term customer relationships and brand strength
	    in the parts side of the business would probably be the most
	    significant challenge for an SPX takeover." Lehman Brothers report
	    by Joseph S. Phillippi, February 18, 1998.

	    * "There appear to be little operational synergies that would aid in
	    achieving these cost savings.  SPX is a manufacturer of shop tools
	    and diagnostic equipment, while ECH [Echlin] is a manufacturer of
	    aftermarket brake systems, ignition parts and OEM fluid delivery
	    tubing."  Morgan Stanley Dean Witter report by John G.
	    Inch/Stephen J. Girsky, February 17, 1998.

	    * "[W]e believe synergisms are largely absent [from the SPX-Echlin
	    combination]." Merrill Lynch report by Darren Kimball, March 17,
	    1998.

SPX Has Repeatedly Mischaracterized Connecticut House Bill No. 5695, Which
Would Amend Connecticut's Business Combination Statutes

      SPX has repeatedly mischaracterized the effect of Connecticut House Bill
No. 5695, which the Company, as well as the Connecticut Attorney-General, the
Connecticut Secretary of State and other Connecticut companies, believe is an
appropriate legislative response to SPX's attempt to thwart the intent of
Connecticut's business combination statutes.


       SPX Claim     "[T]he Echlin Board appears to be pursuing extreme
		     defensive tactics that violate the principles of good
		     corporate governance and could destroy substantial value
		     for Echlin shareholders."

       FACT          Even if House Bill No. 5695 is enacted into law in
		     Connecticut, SPX will continue to have more takeover
		     protections than Echlin:

		     *        SPX has a staggered board.

		     *        SPX shareholders cannot call a special meeting
			      under any circumstances.

		     *        SPX directors cannot be removed without cause
			      during their term.

		     *        SPX directors can be removed for cause only by an
			      eighty per cent shareholder vote.

		     *        SPX's charter contemplates the approval of
			      "continuing directors" for certain business
			      combinations.



       SPX Claim     "[E]ven if 100% of Echlin shareholders voted to remove
		     directors, they could not be removed at a special meeting
		     for a year."

       FACT          Under House Bill No. 5695, directors may be removed for
		     cause at any special meeting, and can be removed at an
		     annual general meeting for any reason. Under SPX's own
		     charter, directors cannot be  removed without cause
		     during their term, and can be removed for cause only by
		     an eighty per cent shareholder vote!

       SPX Claim     "[E]ven if the new board were elected by 100% of the
		     shareholders, the new Board could not approve a business
		     combination -- even one all shareholders wanted."

       FACT          Under Connecticut's business combination statutes, no
		     Board can approve a business combination with an
		     interested (i.e. 10%) shareholder for five years from the
		     date a person becomes an interested shareholder, unless
		     the Board approved the business combination, or the
		     transaction in which the person became an interested
		     shareholder, before the person became an interested
		     shareholder. That's not the effect of House Bill No. 5695
		     -- that's existing Connecticut law. As the Connecticut
		     Secretary of State told the Connecticut General
		     Assembly's Judiciary Committee, House Bill No. 5695 is
		     just a "logical extension" of that law.


       The real issue is whether you want a board dominated by SPX management
to determine, with SPX, whether and on what terms Echlin will be sold to SPX.
As the Connecticut Attorney-General told the Connecticut General Assembly's
Judiciary Committee: "[The Board] will be hand picked and hand bought, sure to
do the bidding of [SPX]." Since the interest of SPX consists in acquiring the
Company at the lowest possible cost to SPX and at the lowest possible price to
the Company's shareholders, the interests of an SPX-
controlled Board will by definition be directly contrary to your interests as
shareholders of the Company.


SPX Has Mischaracterized Its Past Discussions With Echlin

       SPX claims that it must resort to the extraordinary process of a special
meeting to replace the Echlin Board because the Echlin Board has been
"intransigent" or "adamant" in its refusal to sell Echlin to SPX.  SPX would
also like you to believe that it has been attempting to negotiate with the
Echlin Board for over a year. The facts do not bear out these claims.

	  *       Mr. Blystone has admitted in testimony before the Connecticut
		  General Assembly's Judiciary Committee that he had
		  "discussions -- not negotiations" with Echlin's
		  then-Chairman in February of 1997.

	  *       By SPX's own account, no substantive meetings between Echlin
		  and SPX executives occurred until November 1997.

	  *       In the November 1997 meetings, SPX did not come forward with
		  a specific proposal for a business combination or with
		  specific evidence of synergies that would supposedly result
		  from a business combination.

      The Echlin Board is now evaluating the proposed offer which SPX made in
February.  SPX is unhappy about the careful and deliberative evaluation of
SPX's proposed offer that the Echlin Board is undertaking -- and you should
ask yourself whether you, as a shareholder of Echlin, will receive the same
care and concern for your interests if the SPX-controlled board is considering
the SPX offer.
